Find the volume of the solid obtained by rotating the region bounded by the curves
x = y - y^2 and x = 0 about the y=axis. Use the disk or washer method.
First thing to do would be to graph these two expressions. When you do you'll find that there is a section which is bounded by the y axis in sort of a half moon shape, ...
The volume of a solid of revolution is found using the disk method. The solution is detailed and well presented. The response received a rating of "5/5" from the student who originally posted the question.
