Calculates volume of geometric shapes: cube, prism, pyramid, frustum, cone, cylinder, sphere, ellipsoid.

Calculate the Volume and Surface Area of a Sphere with our online calculator

This calculator calculates the radius of a ball from its volume.

If you want to made a DIY sphere, you need to unfold the sphere to 2D shapes, or, more strictly speaking, approximate the sphere using petals, or "orange peels" (also called the lunes) on the plane. The calculator calculates basic parameters of such 2D peel and displays coordinates of points for drawing one peel on a plane.

Volume of hemisphere asymmetrically cut by a flat plane under a given angle.

This calculator is a two-in-one tool that can be used to find the volume of a sphere given its radius, or the radius of a sphere given its volume.
