Staff Review
This is a very useful Calculus lesson finding volume by revolving a graph around an axis. The disk method and washer method for finding volume are explained. The animations of the solids are wonderful for understanding exactly what is going on. Some great classic example problems are shown. This is a truly great lesson for understanding volume of solids.
