# Spherical cap and spherical segment

This calculator computes volume and surface area of spherical cap and spherical segment

A spherical cap is the region of a sphere that lies above (or below) a given plane. If the plane passes through the center of the sphere, the cap is called a hemisphere.

Formulae:

- lateral surface area

- base surface area

- volume

A spherical segment is the solid defined by cutting a sphere with a pair of parallel planes. It can be thought of as a spherical cap with the top truncated, and so it corresponds to a spherical frustum.

Formulae:

- lateral surface area

- volume
