Homework Statement
A torus is formed by revolving the region bounded by the circle x2 + y2 = 1 about the line x = 2. Find the volume of the solid.
The Attempt at a Solution
I've actually got the answer correct. I'm using shell method. My height, h(x), I believe is double the area of the semi-circle, I have 2(1-x2)1/2 and my radius p(x) was 1. I'm integrating over the interval [-1,1] and I got 4pi2 I'm curious if this was the right thing to do or if it makes sense to more knowledgeable people out there. Thanks
