# Math Help - Volume Around x=-r question

1. ## Volume Around x=-r question

The region R enclosed by the curves $x-3 y=-12$ and $y=\sqrt{x-3 }+5$ is rotated about the line $x=-1$. Find the volume of the resulting solid.

Thanks!~

2. Solids of revolution are explained pretty well here: Pauls Online Notes : Calculus I - Volumes of Solids of Revolution / Method of Rings

There's even an example that is very close to your problem.
