# Half Sphere Mass

## Description

A sphere is defined mathematically as the set of points that are all the same distance r from a given point in three-dimensional space. This distance r is the radius of the sphere, and the given point is the center of the sphere. Any plane that includes the center of a sphere divides it into two equal hemispheres (half spheres). The mass of each hemisphere can be calculated by the density of the sphere and its radius.
