Hi, I'm really confused with where to start. I integrated with respect to x first, so that I could plug in y and 0 and then integrate with respect to y after, but I keep getting 0 as an answer after plugging in y and 0.

This is what I got when I integrated with respect to x..

(7x/6)(y^2-x^2)^(3/2)
