1. The problem statement, all variables and given/known data Find the volume of the solid using The Washer Method [tex]y=x^2, x=2[/tex] 2. Relevant equations 3. The attempt at a solution I can solve this problem fine and I don't think my actual question even affects the solution, but I would like to know how one does this. In my text book they say to setup the problem on a graph, no problem there. But I am confused on how one obtains the inner line segment. Actually here is a drawing since I can't explain what I am looking for. How do you find that red line segment? I would think that would matter in the solution, but it doesn't seem to - at least at my level.
