Use cylindrical coordinates to evaluate the triple integral , whereEis the solid bounded by the circular paraboloid and the -plane.

This is giving me trouble and I'm not sure about the limits of integration. The fallowing one is sort of similar and also driving me crazy.

Find the volume of the solid that lies within the sphere x^2 + y^2 + z^2 = 9, above the xy plane, and outside the cone z = 4sqrt{x^2+y^2}.
