How do you SET UP this question? I can probably do it if I set it up, but I just don't know how to set it up. Also, please EXPLAIN how to set it up so I can set up other problems like this.

Let V be the region bounded by the $\displaystyle y-axis$, $\displaystyle y = 8$, $\displaystyle y = 1$, and $\displaystyle y = x^{.75}$. Find the exact volume by rotating V around the y-axis.

My attempt:

$\displaystyle \pi{\int^8}[(8-x^{.75}+1)^2]dx$

. .$\displaystyle ^0$
