Answer 3

To recap, you should have (so far)
\[\begin{align*}
6.&&\pi\int_1^2\left((\sqrt{y-1})^2-(1-y)^2\right)~dy\\
7.&&\pi\int_0^1\left((x+1)^2-(x^2+1)^2\right)~dx\\
8.&&\pi\int_1^2\left((y-2)^2-(\sqrt{y-1}-1)^2\right)~dy
\end{align*}\]

Answer 4

\[\begin{align*}9.&&\pi\int_0^1\left((1-x^2)^2-(1-x)^2\right)~dx\end{align*}\]
