Find the volume of the solid formed by the revolving the region around a line I have to find the volume of the solid formed by the revolving the region enclosed by $x=\frac{y^2}4$ and $y=x^5+x^3$ around the line $y=2$ I know how to find the volume when it revolve around x-axis, but when it revolve around a function line or y-axis, how should I approach it? Appreciate anyone help

Transform $y$ into $y-2$, so that line $y=2$ is transformed into the $x$-axis. The two equations become $y=x^5+x^3-2$ and $y=2\sqrt x -2$.
