Find the surface area.Find the surface area formed by revolving the upper semicircle y=9-x2 y =sqrt {9-x^2}  on  0≤x≤2 0 le x le 2  about the x-axis. We have practiced the shell method with vertical strips (dx). In this problem, try using the shell method with horizontal strips (dy). Use the same formula:  V=2π∫(radius)(height) dy V = 2pi int (text{radius})(text{height}),dy           Find the volume of the solid obtained by revolving the region bounded by                       x=y2, x=0, 0≤y≤2 x = y^2, quad x = 0, quad 0 leq y leq 2               about the x-axis, using the shell method with dy.           (a) Express the radius and height in terms of y.           (b) Set up the integral for the volume.           (c) Evaluate the integral to find the exact volume.
