In each part below, set up an integral in x equal to the volume V of the solid obtained by rotating the region shown below about the specified axis. [Note that the "dx" is already written outside the box, so do not include it in your answer.] y = 8xe-*, y = 0, x = 2; (a) Rotated about the x-axis V = / dx (b) Rotated about the y-axis V = dx Submit
