Sec7.3: Problem 4 (1 point) Book Problem 8 Let V be the volume of the solid 8 obtained by rotating about the y-axis the region bounded by y : N/ 72.11: and y : 332. Find V both by slicing and by cylindical shells: (A) The method of cylindrical shells : The circumference of a typical shell = and the height of this shell = The volume V = I: do: , where a = and b 2 Therefore V = (B) The method of slicing from Sec(7.2): The volume V = f: dy , where a = and b 2 Thus the volume V =
