6. (15 pts) Use either Stokes theorem or the Divergence theorem (whichever is applicable) to calculate ffs Ail-(15" where S is the closed surface given by the paraboloid z = 9 (12 + 312), and the disc {3:2 + y2 S 9, z = 0} and F'(:c,y,z) = (23, y", :53). The surface is oriented with outward pointing normal
