Which Planet is Largest?
Journal of Online Mathematics and Its Applications
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
