) Let be the piece of the surface z = 1y 2 inside the cylinder x 2+y 2 = 1 oriented upward. (Hint: try x = u cos v, y = u sin v as part of the parametrization.) Compute each of the following. Set up each as a double integral but use an integral calculator to compute them. (a) the surface area of . (b) the average value of g(x, y, z) = z on . Recall
