Use polar coordinates to find the volume of the given solid:
Inside both the cylinder $x^2 + y^2 = 4$ and the ellipsoid $4x^2 + 4y^2 + z^2 = 64$
The limit of integration for the radius goes from 0 to 2 because the problem asks for the solid inside the cylinder? If it asked for the solid between the cylinder and ellipsoid it would be from 2 to 4?
