# College Calculus: Level I Volume by Method of Cylindrical Shells

In this video we are going to take a look at computing volumes using integration by means of the Method of Cylindrical Shells. This tutorial naturally follows after the one about the Method of Disks and Washers. This is a different approach to compute the same types of volumes. Method by Cylindrical Shells is used for calculating the volume of a solid of revolution, when integrating along an axis perpendicular to the axis of revolution. This is in contrast to Disk Method which integrates along the axis parallel to the axis of revolution. Examples that will be used here are identical to the ones used in previous tutorial and we will get identical numerical results at the end.

This is a very good question, I asked it myself. I wish someone would answer the questions....

Why do you draw two different cylindrical shells? In class only one was drawn.
