I have a question that I cannot figure out for anything. I have to solve this using the shell method. If somebody can help me out, that would be great.

Rotate the region bounded by the given curves about the line indicated. Obtain the volume of the solid by the method of shells. (give your answer in terms of .)
, - axis, - axis; about the - axis

I have no idea how to set up the integral. If somebody could show me how to set up the integral and how to find the limits of integration, I think that I can handle it from there. If you feel the need to solve it out, that would be great too. I have worked on this thing for a couple of hours and am just spinning my wheels.......

Thanks in advance for all the help.
