Define R as the region bounded above by the graph of the function f (x) - vx and below by the graph of the function g (x) - - over the interval [1, 4] Find the volume of the solid of revolution generated by revolving R around the y-axis. The radius of the shell is given by x. Round the answer to two decimal places. 9(x) - 4 3 1( x ) = x NX -X 2 2 1 R 1 5 -4 5 -2 -1 2 3 2 x Refer: use shell method Show your work.
