LetSbe the region bounded betweeny=12xandy=√x.(a) (2 points) Draw a nice sketch ofS. Also, find and label the intersection points of the two curvesin your sketch.(b) (3 points) Set up an integral (don't worry about evaluating it) to find the volume of the solidgenerated by revolvingSabout the linex= 4 using the disk/washer method.(c) (3 points) Set up an integral (don't worry about evaluating it) to find the volume of the solidgenerated by revolvingSabout the linex= 4 using the shell method.(d) (3 points) Set up an integral (don't worry about evaluating it) to find the volume of the solidgenerated by revolvingSabout the liney=−2 using the disk/washer method.(e) (3 points) Set up an integral (don't worry about evaluating it) to find the volume of the solidgenerated by revolvingSabout the linex=−2 using the shell method.
