Without evaluating the integral, set up the integral that represents:
4.1) The volume of the surface that lies below the surface z = 4cy - y^3 and above the region D in the xy-plane, where D is bounded by y = 0, x = 0, x + y = 2, and the circle x^2 + y^2 = 4.
4.2) The volume inside the paraboloid z = 16 - x^2 - y^2, and outside the cylinder x^2 + y^2 = 9, and above the xy-plane.
4.3) A change of order of the integral:
∫∫(0 to 3)∫(0 to 9) y cos(x^2) dx dy
