"Use the method of cylindrical shells to find the volume V of the solid obtained by rotating the region bounded by the given curves about the x-axis."
I have two equations : x= 2y^(2)-y^(3) and x= 0. I am supposed to rotate about x axis. I'm stuck on what region I am looking at for rotation. I got x=0 being the y axis, and the other equation to look something like a sin(x) curve. The area rotate is not very intuitive for me.
