Why is the volume of a sphere V=4/3*pi*r^3? (calculus disk method)

This tutorial covers why the sphere with radius r has the volume V=4/3*pi*r^3. We will prove this by using the disk method for the volume of a solid of revolution. This is an application of integration that you will learn in your Calculus 2 class.
