bounded by the paraboloid z=4x^2+4y^2 and the plane z=a (a>0) if S has constant density K.

I just need someone to explain to me how to set up the integral using cylindral coordinates.

We first note that . To find using cylindrical coordinates, we let

Our paraboloid equation becomes

and the equation of intersection of the paraboloid with the plane becomes

Our integral becomes

where
