So, I'm quite rusty on Calculus and was wondering if anyone could offer some help-- I'd really appreciate it! I'm also new to this site so pardon if I don't know how to format things.

1) I'm asked to find the volume of a solid by rotating the region bound by^3, y=8, and x=0 about x= -4 by using the disc/washer method.

I'm unsure how to proceed because I don't know if I'm supposed to set them all up to solve for y or x because I have both y=8 and x=0. Since I'm rotating around the vertical line, x=-4, would I solve for y? And if so, how do I set up the integrals y=8 and x=0?

2) I I'm asked to find the volume of an area bounded by y=5 and y=x+(4/x) that revolves about x= -1. When I set up the integral, which function goes first?

I'd appreciate any assistance!
