PI, not pie!!!
The center of gravity is clearly on the x-axis, so we just need to find the x-coordinate.
Recall that
x-bar = (integral x*f(x) dx)/(integral f(x) dx)
the curve y^2 = x(1-x)^2 between x = 0 and x =
1, rotates about the x - axis through 2pie
radians. Find the position of the centre of
gravity of the solid so formed.

I'm sure your text has examples of finding the centroid.
If you are unsure about the shape, just see
