1. The problem statement, all variables and given/known data http://faculty.tcu.edu/richardson/Calc2/H20090323torusVolume.htm [Broken] This is a link to the homework. 2. The attempt at a solution I did number 1 by doing 2 * integral from -2 to 2 of sqrt(4-x^2) = 4pi The second problem is where im completely confused and dont know how to do it or even conceptualize it. Trying to look at an example of a similar problem on another site, I tried to do 4pi * integral from -2 to 2 of xsqrt(4-x^2) but it equals 0. I think if I understand this one ill be able to do the rest of the homework.
