Can someone plz help me w/ these problems below: Find the volume generated by revolving the area abounded by x=y^2 and x=4 about a)the line y=2 b)the line x= -1 ***I tried to write out the integral not sure if it's correct: a) V=pi* int. of (sqrt(x)^2-(2-sqrt(x))^2) dx **integral form 0->4 ?? b) V=pi* int. from -2->2 of (4-y^2)-1^2 dy ?? If the integrals is wrong plz fix it for me...Thanks!
