Geometry Formula Solver

Triangles, arcs and volume

$1.99 · Designed for iPad. Not verified for macOS.

Know two values? Solve the right triangle and keep the formulas close. Calculate circular segments and solids, then copy or share results. Solve a right triangle from the two values you know, then copy a result or share the calculation. RIGHT TRIANGLES Choose two legs, hypotenuse and angle, base and angle, or hypotenuse and base. See missing lengths, both angles, area and perimeter. Angles must be greater than 0° and less than 90°. MINOR CIRCULAR SEGMENTS Enter radius and chord to calculate central angle, arc length, sagitta and segment area. The chord cannot exceed the diameter. SOLIDS Calculate cylinder, cone and sphere volume and total surface area. A sphere needs only its radius. Expand the formulas when needed. Decimal point, decimal comma and scientific notation are supported. Use one length unit throughout: areas are in units² and volumes in units³. Displayed results are rounded; copying and sharing retain calculation precision. Pay once. No account, ads, subscription, tracking or synchronization. Calculations run on device. Numeric inputs return to the original examples on relaunch.

  • This app hasn’t received enough ratings or reviews to display an overview.

A cleaner calculation workspace, labelled geometry diagrams, 11 interface languages and individual result copying. Improved invalid-input handling and accuracy for very small circular segments.
