Jim Braselton has been teaching math in the Department of Mathematical Sciences at Georgia Southern since 1990. He is interested in incorporating various technologies, especially computer algebra systems like Mathematica and Maple, into the college mathematics curriculum and areas of applied mathematics. Besides teaching calculus, Jim enjoys canning vegetables and touring the AKC dog show circuit with his German Shepherds, Rose and Ted.
For some students, using the methods of washers or cylindrical shells to find the volume of a solid obtained by revolving a given region about a given line is difficult to understand because of the abstraction involved. In this article, we use on-line resources and computational tools to approximate the measure of the volume of the space occupied by each planet as it orbits the Sun.
