Let S be a solid bounded by the xy-plane, on the side by the cylinder $\displaystyle x^2+y^2=2x$ and above by $\displaystyle x^2+y^2+z^2=4$.

Set up a triple iterated integral in rectangular coordinates which represents the volume of the solid S.

I know that the first integral is dx from 0 to 2, but how to obtain other?
