Use cylindrical coordinates to evaluate the triple integral ∫∫∫sqrt(x2+y2)dV where E is the solid bounded by the circular parabaloid z=9−16(x2+y2) and the xy plane.
Convert this to cylindrical coordinates. Find the shape that the function z intersects the xy plane. The bounds of this region in the xy-plane will determine the bounds on r and theta, and z will be bound between the function and the xy-plane.
