hello. i am not quite sure how to solve these problems when they aren't revolving around the x or y axis. for example:

area within y=x^4 , y=1

revolving around y=8

What do I do?

Well, that's what I thought too, but apparently my answer is wrong.

Try using shells.

$\displaystyle 2{\pi}\int_{0}^{1}(x-8)(x^{4}-1)dx$
