Use the washer method to find the volume of the solid generated by revolving the region bounded by and about the -axis.

Start by determining the points of intersection. The -values of the points of intersection will be the bounds of your integral (this is rotation about the -axis, so the width of the washers is ).
The general formula for the washer method is:
Which function is the outer radius and which function is the inner radius ?
