A uniform plate of height H = 1.96 m is cut in the form of a parabolic section. The lower boundary of the plate is defined by: [tex]y=.35x^2[/tex]. The plate has a mass of 7.27 kg. Find the moment of inertia of the plate (in kgm2) about the y-axis.

I have absolutely no clue where to start... I know [tex]I=\int(r^2)dm[/tex] but I'm not sure how I can relate this to this problem.
