Volume of spheres

The volume of a sphere is given by:

 $V=\frac{4}{3}\;\pi\;r^3$ where r is the radius of the sphere.

Find the volume of the sphere:

 $V=\frac{4}{3}\;\pi\;r^3$ $V=\frac{4}{3}\;\pi\;\cdot\;6^3$ $V=\frac{4}{3}\;\pi\;\cdot\;216$ $V=288\;\pi$ cm3 V=904.32 cm3

What is the volume of this cone when r=9?

Use $\pi$=3.14
