Consider the region R bounded by f(x)=x^3, y =1, and x = 2. Find the surface area when f(x) is revolved around the line x=5.
I know that the equation for surface area is the intergal from a to b of 2pi*r*h dx
in all of the examples that I had done in class, everything was around the x or y axis. I don't even understand how to get my r or my h in this case. If anyone has any suggestions, it would be greatly appreciated.
