9-10.

Use the washer method to find the volume of the solid generated by revolving the region bounded by and

*-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*

*?*
