1. The problem statement, all variables and given/known data Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis. 2. Relevant equations y = x^2 +1 , y = 9-x^2: about y = -1 3. The attempt at a solution I used disks. I said that r = 1 + ((9-x^2)-(x^2 +1 )) = 9 - 2x^2 So my integral all together is V = ∏ ∫ (9 - 2x^2)^2 dx from [-2,2] Does this set up look correct.???
