Let's look at the geometric characteristics of a sphere. But first, please review the definition of Volume Of Three-Dimensional Shapes, and Cubes And Perfect Cubes.

- A sphere has a very unique feature, all points on the surface of the Sphere are equal distance from the center of the Sphere; or said another way, the distance from the center of a Sphere to the surface is equal to the radius.
- Special note, the radius of a Sphere must be greater than zero.

**Volume Of A Sphere Formula**

Formula = ^{4}/_{3} × Pi × Radius^{3} =

Formula = ^{4}/_{3} × π × r^{3}
