1. The problem statement, all variables and given/known data Find the volume of the solid formed by rotating the region inside the first quadrant enclosed by y = x^2 y = 2x 2. Relevant equations 3. The attempt at a solution Okay, so I first solved both equations for y, which gave me x=radical(y) and x=y/2. Then I graphed both of them, found that the radical one was above the y/2, so I made the equation pi*(radical(y)^2 - (y/2)^2. I then made that equation a definite integral with lower limit 0 and upper limit 2. Of course, it turned out wrong (I'd use Latex to make it look nice, but it's not coming out very well right now and I don't have the patience). Suffice it to say, I did something wrong somewhere.
