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 about the x-axis. 2. Relevant equations V= pi* integral [a,b] r^2 3. The attempt at a solution So i used intergral 0 to 2 (2x-x^2)^2 dx this is wat i got.... pi*(((2^5)/5)-(4(2^4)/4)+(4(2^3)/3)) its wrong so wat did i do wrong?
