1. The problem statement, all variables and given/known data Find volume of the solid generated by revolving the region bounded by x = y^2, x=4 about the line x = 5 2. Relevant equations the washer method from c to d ∏∫ R(y)2 - r(y)2 3. The attempt at a solution I set r(y) = 1 and R(y)= y^2 and got the integral from 0 to 2 of ∏∫(y^2)^2-(1)^2 I got an answer of 16.96 but i know this is wrong because the back of the book gives a different answer. Please tell me where I went wrong.
