1. The problem statement, all variables and given/known data How do you find the volume of the solid obtained by rotating the region bounded by the given curves about the specified lines? I keep getting a negative number and I"m becoming so frustrated! 11pi/30 is the answer in the textbook. Thank you so very much in advance! 2. Relevant equations y=x^2 x=y^2 about y=1 3. The attempt at a solution Area: pi[(1-x^2)^2 - (1-x^(1/2))^2)] Integral: pi[1-2x^2+x^4-1+2x^(1/2)-x) between x=0 and x= 1 Antiderivative: pi[(1/5x)^5-(2/3)x^3 + (2/3)x^(3/2)-(1/2)x^2] Soln: pi((2/10)-(5/10)) = -3pi/10???????
