A filled semicircle as above but with respect to an axis collinear with the base

As shown in the figure, second moment of area of a filled semicircle on the x-axis collinear with the base is,

Ix  = (¥ð/8)*r^4

Also, the second moment of area Iy about the y-axis on the centroid is equal to Ix.

Iy = Ix
