Applications of Integration - Volume of Revolution (y-axis)

Volumes of Revolution - Disk/Washers Example 1. A problem is shown about how to use the disk/washer method to find a volume of revolution about the y axis.

This calculus video tutorial explains how to use the disk method and the washer method to calculate the volume of a solid when the region enclosed by the curves are rotated around the x axis, y axis, and non axis or another line parallel to the x or y axis. This video contains plenty of examples and practice problems for you to work on. It shows you how to set up and evaluate the definite integral. Techniques include expanding a binomial expression and basic integration rules.

Another pretty basic integration question, good if you want to just get the process on lock though.
