Circle Calculator vs Geometry

Know one measurement of a circle? Get all the others instantly. Type the radius, diameter, circumference or area – whichever you have – and Circle Calculator fills in the other three and writes every value right on the drawing. RING (ANNULUS) Enter the outer circle and the hole to get the ring area and ring width, plus both circumferences and the hole area. Ideal for pipes, washers, gaskets and round frames. ARCS, SECTORS & CHORDS Enter a radius and an angle, or a radius and an arc length, to get the arc length, chord and central angle. With Pro, also get the rise (sagitta), sector area, segment area and perimeter – and find the radius of any curve from its width and height (chord + rise), ideal for arches, curved walls and bends. SEE HOW IT'S SOLVED Every result comes with its formula and your numbers plugged in, for example C = 2πr = 2 × π × 5 = 31.4159. TYPE IT YOUR WAY Enter π and √ right in the field (3π, 5√3), use 3.14, 3.1416, full-precision π or your own value, and show 0 to 10 decimal places. Decimal comma or point both work. DRAWING OR CLASSIC Values sit directly on the circle in the Drawing layout. Prefer a list? Switch to Classic in Settings. FORMULA LIBRARY & HISTORY A searchable reference of circle, ring, arc and sector formulas with worked examples, and a history of your calculations to reopen any time (free keeps your last 5). EVERYWHERE YOU WORK iPhone, iPad and Mac, portrait or landscape, light or dark mode – in English, German, Japanese, Turkish, Spanish, French, Italian and Russian. On iPad and Mac: a sidebar, a full-height drawing and keyboard shortcuts.

The GeometrySolver is not just an app, its a canvas and a book too. This app not only solves the geometric shapes, it also teaches you the formulas related to each geometric shape as well as it draws the geometric shapes when solved. This app is designed by an engineer to the perfection with every details in mind. It calculates side, height, diagonals, apothem, diameter, radius, perimeter, circumference, area, lateral area, surface area, volume. Some shapes have a dedicated interactive tab to play around and draw those shapes of different dimensions. Each geometric shape has its corresponding formulas written beautifully in mathematical way. This is a perfect app for your kids to learn geometry interactively. Draw, solve, share the geometric shapes. Drawn/solved shapes are displayed with their properties (numeric values). The Solve tab of angle is dynamic and interactive. You can touch/drag on the surface to draw an angle or use the slider to draw an angle. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. There are so many common geometric shapes to learn from like square, circle, cylinder, cone, cuboid, pyramid, sphere and more There is also a Study page to help you with learning formulae related to many common geometric shapes. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
