Use this calculator to calculate properties of a regular polygon. Enter any 1 variable plus the number of sides or the polygon name. Calculates side length, inradius (apothem), circumradius, area and perimeter. Calculate from an regular 3-gon up to a regular 1000-gon. A rechargeable stylus is included with the laptop, the "HP Rechargeable MPP2.0 Tilt Pen." (MPP is short for Microsoft Pen Protocol.) It's round with one flat edge that connects to the left side of the laptop with magnets. That flat side also has two customizable buttons The screen, on the other hand, is less so. The 14-inch IPS touch panel is limited to 1,366-by-768-pixel resolution, which results in a dull picture when playing videos and viewing images. Its low 220-nit rated brightness doesn't do it any favors, either. The display is a disappointment, especially considering this a convertible laptop. A 14-inch screen at such a low resolution just isn't much fun to use, and the glossy, reflective surface makes finding the right viewing angle difficult. You might get away with 1,366 by 768 in an 11-inch Chromebook, but the coarseness of the resolution is obvious at this screen size. So, of course, we attempted to play a few games on the HP Spectre x360. As we've mentioned, this definitely isn't a gaming laptop, but we wanted to see if it would be possible to play games at the end of the day, when you want to unwind after a hard day at work. The Spectre x360 14's 1920 x 1280-resolution panel covers 75% of the DCI-P3 color gamut, making it more colorful than the panel on the XPS 13 2-in-1 (70%) and about as vibrant as the Yoga 9i's (76%) 14-inch display. The competition is no match for the Spectre x360 14's 3K2K OLED display option, which covers an astonishing 140% and demolishes the category average (86%).
While the Spectre x360 is undoubtedly a premium device, it has the kind of bloat you would expect from some budget machines. As for the typing experience, it's rather good. The keys, though shallow, are snappy and bouncy. While I frequently bottomed out, the keyboard was comfortable enough to where I didn't feel the need to use that precious USB Type-A port to connect my mechanical gaming keyboard. And those with larger hands will appreciate the keys' large size and generous spacing. We also run a custom Adobe Photoshop image-editing benchmark. Using an early 2018 release of the Creative Cloud version of Photoshop, we apply a series of 10 complex filters and effects to a standard JPEG test image. We time each operation and add up the total (lower times are better). The Photoshop test stresses the CPU, storage subsystem, and RAM, but it can also take advantage of most GPUs to speed up the process of applying filters. Though it was next to last in this group, the Chromebook x360 14c's unplugged time of nearly 11-and-a-half hours indicates you'll have no trouble getting through a day of work or school.HP's B&O-tuned top and bottom-firing speakers delivered a sonic punch when I listened to LEISURE's "Lonely Nights," a funky alternative-pop song. There was a nice depth to the drum hits and a clear sizzle to each tap of the hi-hat. The vocals were crisp but overshadowed, and some of the treble tones of the electric guitar were peaky.
Another tie for the Chromebook x360 14c and the Spin 713, with the Lenovo claiming the bronze medal. These aren't the fastest Chromebooks we've ever tested, but they're solid contenders. While the Spectre x360 certainly isn't one of the best gaming laptops out there, it could feasibly run some of the best PC games that don't have especially steep hardware requirements and will definitely do better than a lot of other thin and light laptops out there. Impressively, the HP's dual-core Core i3-10110U goes toe to toe with the Core i5 of the Acer. The Pixelbook Go's 5-watt Core i5 brings up the rear.While the HP Chromebook x360 14a's chassis is solid, the same can't be said for its touchpad, which is dodgy and slow to respond. It made navigation a stumbling area at times during testing, ruining the system's otherwise smooth performance. The touch screen, on the other hand, is responsive and easy to use, both in landscape and portrait orientations. The B&O-branded sound system isn’t the loudest I’ve ever encountered, maxing out at 70.2dB(A) against a pink noise source at a 1m distance, but there is a decent amount of bass, and the overall soundscape is very nicely balanced with ample detail and space. The Spectre needed 17 minutes and 2 seconds to convert a 4K video into 1080p resolution, a decent result though slower than the XPS 13 2-in-1 (15:52) and the Yoga 9i (14:24). The Spectre landed right around the category average (17:13) and finished several minutes before the Galaxy Book Flex 15 (22:18). An image I took at my well-lit desk was color accurate, catching my navy shirt, blue eyes and the mixed shades of brown in my hair and blue. But overall, the picture was grainy, and light coming in from some nearby windows was blown out.
HP Documentation: Contains warranty information, regulatory, safety, and environmental notices, and the user guide. The Pavilion was just a whisker short of the 4,000 points that we consider excellent in PCMark 10. It joined the other SSD-based convertibles in breezing through PCMark 8's storage subtest, cementing its status as a solid productivity partner. Like models in the UK and US, there are numerous configurations available, including models with 14-inch and 15-inch screen sizes. The Spectre's palm rejection worked pretty well, and the stylus worked well with both tilting and shading in supported applications. In Paint 3D, using the crayon tool required extra pressure for a deep hue, just like the real thing. I do wish, like some of Microsoft's styluses, that HP would add an eraser to the end. This gaming simulation defeated the laptops just as 3DMark did and just as real games would. Again, these machines aren't intended for gamers. You might eke out some decent play with the Radeons at 720p and low settings, but even that is a stretch for anything beyond casual games. Battery Rundown Test
Convertible Chromebooks Hit the Test Bench
The Intel Iris Xe graphics employed by the Spectre x360 14 reached a respectable 4,229 in the 3DMark Fire Strike benchmark, topping the XPS 13 2-in-1 (3,847) and Galaxy Book Flex 15 (2,215) but falling just short of the Yoga 9i (5,014) and the category average (4,488). Unfortunately, we had to drop graphical settings to low, and scale down the resolution, to achieve smooth gameplay. As such, while it was possible to play modern games such as Ori and the Will of the Wisps, it was only with big sacrifices to graphical fidelity. So, don’t give up the day job, Spectre x360. We tested the HP Pavilion x360 14 (model 14m-dy0113dx) with a 1080p IPS display, an Intel Core i3-1125G4 CPU withintegrated Intel UHD Graphics G4, 8GB of RAM, and a 256GB SSD, in the Natural Silver color scheme. All the components are configurable, but keep in mind that most vendors, including HP, sell this laptop as a pre-built model with a pre-determined configuration instead of letting customers choose the parts individually. As a result, it may be hard to find the exact configuration you want. The following formulas were used to develop calculations for this calculator where a = side length, r = inradius (apothem), R = circumradius, A = area, P = perimeter, x = interior angle, y = exterior angle and n = number of sides. Cinebench is often a good predictor of our Handbrake video editing benchmark, in which we put a stopwatch on systems as they transcode a brief movie from 4K resolution down to 1080p. It, too, is a tough test for multi-core, multi-threaded CPUs; lower times are better.
However, one of the biggest upgrades to come alongside the new Tiger Lake CPUs such as the Intel Core i7-1165G7 is the inclusion of Intel Iris Xe graphics. This is an integrated GPU that promises to offer vastly improved performance compared to previous integrated graphics, and could even rival some discrete GPUs. The HP Pavilion x360 14 2-in-1 laptop is available in a variety of Intel Tiger Lake CPUs. There's the Pentium Gold 7505 and Core i3-1115G4, which are both dual-core CPUs, as well as the Core i3-1125G4, Core i5-1135G7, and Core i7-1165G7, all of which are quad-core CPUs. Every option has Intel Hyper-Threading Technology, which allows multiple threads to run on a single core, accelerating performance in most modern applications and helping make multitasking smoother. The Spectre transferred 25GB of files at a rate of 533.61 MBps, faster than the XPS 13 2-in-1, but slower than the ZenBook Flip S (979.37 MBps). HP’s MSRP is subject to discount. HP’s MSRP price is shown as either a stand-alone price or as a strike-through price with a discounted or promotional price also listed. Discounted or promotional pricing is indicated by the presence of an additional higher MSRP strike-through priceSince this is a slim 2-in-1 laptop, there isn't much room for air or liquid cooling to keep the machine running at optimal temperatures. However, the built-in fans do a decent job of drawing waste heat away from vital components like your CPU and forcing it out of the vents in the bottom of the laptop. The screen gets bright enough for most settings, and in our testing we recorded an average brightness of 365 nits across the whole display. That's as good as Apple's latest MacBook Air (365 nits) but a bit short of competitors like the Dell XPS 13 (469 nits). The colors look great, too; in our testing the HP Spectre x360 14 with a 1920 x 1080 FHD display covered 105.3% of the sRGB color spectrum, beating out the XPS 13 (97.9%) but falling behind the MacBook Air (114%). The previous HP Spectre x360 also performed well in this test, scoring 10 hours and 55 minutes. Nevertheless, the extra half an hour is welcome, and it means the more powerful components haven’t come at the cost of battery life. The biggest upgrade on the HP Spectre x360 (2021) over the previous model are its components and performance, with the laptop being a showcase for Intel’s latest mobile processors. There’s no doubt about the inherent versatility of the design, though, especially if you want to use a stylus for sketching or note-taking. Even a rather heavy tablet is a lot easier to work on than the screen of a conventional laptop with a keyboard that keeps getting in the way. Design and Keyboard
