centroids

[anillatoo]

Find the coordinates of the centroid of the finite region bounded by the x-axis and the curve whose
equation is
y = x^2(1 − x). Ans = (3/5,2/35)
Deduce the coordinates of the centroid of the finite region bounded by the x-axis and the curve whose
equation is
y = x(1 − x)^2. Ans = (2/5, 2/35)

I have done the first part using the standard formula for centroids but the second part, it says deduce, but I don't know how to use the fist part to do the second one? Any help please?

ull have to do the whole thing again
deduce means just find it out like u did for the first one!
