When an individual strip under the function is revolved around an axis, it creates a circle of a given area. If the areas of each of these circles under the function are added together, we get the total volume of the Solid of Revolution http://www.youtube.com/watch?v=GUwUYFoG-84&feature=related The Disc Method
