If 0≤f(x)≤g(x) for x in the interval [a, b],can the surface obtained by rotating the graph of y=g(x) around the x-axis over the interval have less surface area than the surface obtained by rotating the graph of y=f(x) around the x-axis over the same interval? I have heard yes and also no so I would like some clarification. Thanks
