I know the general idea on how to solve these problems, but there are a few here that I'm really not sure on how to solve. I would appreciate any help.

1. Find the volume of the solid obtained by rotating te region bounded by the given curves about the specified line.

y=1/x^5, y=0, x=3, x=4

about x=-3

2. Find the volume of the solid obtained by rotating the regin in the first quadrant bounded by the curves

x=0, y=1, x=y^15

about the line y=1
