Using the cylinder method, set up the integral which computes the volume of the solid generated by revolving the region bounded by the graphs of f(x) = 3 va , x = 9, and the x-axis when the region is rotated about the line x = -2. Do not evaluate the integral. 2T (-2-x )(3vx)dx O 21 ( x - 2) (3vx)dx 2 Tt [ x ( 3 v x ) dx 21 (x + 2) (3vx)dx
