Set up an integral that uses the disk method to find the volumeof the solid of revolution obtained by revolving the area betweenthe curves y = sech(x/2), y =2, x =0 and x = 4 around the line y=2.Include a sketch of the region and show all work to integrate and.Note: Recall that sech(u) = 1/cosh(u).
Please show details for every single step
