Geometry Solver - Free Online | FunToolX

Select a geometric figure (triangle, rectangle, circle, trapezoid, parallelogram, sphere, cylinder, cone, etc.), enter known parameters (side length, radius, height, angle, etc.), and the tool automatically calculates area, perimeter, volume, surface area, etc.

For example, a triangle: Enter the lengths of the three sides and use Helen's formula to calculate the area; enter the base and height to directly calculate the area. Circle: Enter the radius and calculate the circumference (2πr) and area (πr²). Sphere: Enter the radius, calculate the volume (4/3πr³) and surface area (4πr²).

Tools display calculation formulas and steps to help understand geometric principles. Suitable for students to do homework, engineers to quickly calculate, or measurement problems in daily life.

Geometry solver, which inputs known parameters to calculate area, perimeter, volume, etc., and supports various shapes such as triangles, circles, rectangles, and spheres.
