Use the method of cylindrical shells to find the volume generated by rotating the region bounded by the given curves about the y-axis. y = 9ex y = 0, x = 0, X= 1 9n( e - 1) X S Enhanced Feedback : Please try again. Recall that the volume of a solid obtained by revolving around the y-axis a region under the curve y = f(x), from a to b, is b 2xxf(x)dx, where 0 s a
