The volume obtained on revolving about $x=a/2$, the area enclosed between the curves $xy^{2} = a^{2}(a-x)$ and $(a-x)y^{2} = a^{2}x$ is ......$?$
I've drawn both curves and both intersect at $x=a/2$, but the line $x=a/2$ lies in middle of both curves. Now, I have no idea how to find the volume of solid. I know the formula, but don't know if area enclosed between both curves is symmetric about $x=a/2$, so that I can find the volume for one curve only. If area is not symmetric then how would I find the generated volume$?$
