The Geometry help lesson video below shows
you how to calculate the volume of a sphere using the volume of
a sphere formula which will be discussed below. To calculate or
find the volume of a sphere, we need to define a math
term that is key to the formula of the volume of the
sphere; the radius of the sphere.

The radius of a sphere is usually denoted by
r and is the distance from the center point of the sphere to
the surface of the sphere.

In case you missed the formula, here is the
formula of the volume of the sphere again.
