Much help would be appreciated here. The equation is 1/(1+x^2). It is bounded by y=0, x=0, x=2, and is rotating about x=2. I know solving the volume would be much easier through cylindrical shells. The equation through shells would be the integration of 2pi(2-x)(1/1+x^2) from 0 to 2. When I calculated the volume through this method my answer was near 8.5. However, when I solved this through the washer method, my answer was no where close. I would appreciate it if someone can help me in solving this equation through the washer method.
