1. The problem statement, all variables and given/known data Find the volume of the solid obtained by rotating y=x^2 and x = y^2 about y=2 2. Relevant equations V= 2πrh 3. The attempt at a solution When I had constructed the graph I determined the following: r= 2-(y(1/2)) h= 1-y2 after converting V into an integral I applied fundamental theorem of calculus. 2-2y^2-y^(1/2) + y^(5/2) evaluating the expression from lower limit =0 to upper limit = 1 I obtained a value with a denominator of 21. The final answer I should receive is 31π/30 (I proved this by disk method and this is the stated answer).
