hi again : D thanks for all of the help so far, but I think I'm missing some concept here. How do you get Itotal if the radius of the plate is uneven.

as for the question, I think I calculated the I for the disk, but I don't know how to get the total rotational inertia.

Homework Statement an irregularly shaped plastic plate with uniform thickness and density (mass per unit volume) is to be rotated around an axle that is perpendicular to the plate face and through point O. The rotational inertia of the plate about that axle is measured with the following...
