(1 point) Book Problem 11 (A) Use the method of cylindrical shells to find the volume V of the solid S obtained by rotating the region bounded by the given curves about the x-axis: y = x, x = 0, y = 32; The circumference of a typical shell in terms of y = The height of this shell in terms of y = The volume V = fa dy, where a = and b = Therefore V = (B) Use the method of slicing to find the volume V of the solid S: The volume V = f Thus the volume V = dx, where a = and b =
