What is the volume of a sphere with a diameter of ##28 cm##?

If the diameter is 28 cm, then the radius is half that so radius is 14 cm.

From there, we can just use the volume of a sphere formula, which is

##4/(3) pi r^3##

We can just plug in for r and get

##4/3 pi (14)^3##

Plug in and the answer is

11494.04 cm cubed
