Calculus III problem?

If you could solve the problem below and show me the steps you used to solve it that would be really helpful. Set up the integral for the divergence theorem both ways. Then find the flux. F(x,y,z) = x^2 i + xy j + z k E is the solid bounded by the paraboloid z = 9-x^2-y^2 and the xy plane. The first two times I tried to solve it I came up with the answers 81pi, then 36pi - (81/2)pi, and neither of those were correct.
