Easy question:

Find the centroid of x=2-(y^2) and the y axis

2. Relevant equations

3. The attempt at a solution

Already calculated, I got an area of (4/3)(√2)

Cx = 4/5

Cy = 0

When calculating Cx, in the book they have:

Integral (x)(√(2-x))

And go straight to this answer:

[(16/15)√2)].

When I did it, I did it the longer way but got the same thing, how in 1 step do they get this answer?
