1. The problem statement, all variables and given/known data Find the volume of the solid obtained by rotating the region under the graph of y=1/x and y=1/x^2 about the vertical axis x=-1 Also given are points on the y-axis (0,2) and (0,5). I guessing these points are specific sections of the graphs where we find the volume. 2. Relevant equations Volume of revolution = pi int_a^b ((R^2)-(r^2))dx 3. The attempt at a solution For this problem I would think... a=2 b=5 but I am uncertain as to how to find R and r. I know they correspond the outer and inner radii but how do I go about find them. I attached a picture of what the problem looks like.
