The volume of the solid obtained by rotating the region bounded by y=(x^2), y=3x about the line y=9 can be computed using cylindrical shells via an integral V=∫_______________dy (with lower limit of alpha and upper limit of beta) with limits of integration alpha=0 and beta=9 P.S. I have already asked this question but the given answer of V=∫(2pi)(y-9)(sqrt(y)-(y/3)) is incorrect.
