in my hw the question wants from me to find the moment of inertia of(adsbygoogle = window.adsbygoogle || []).push({});

right triangle with the y-axis

as shown in the attatchment

note: the mass of the plate is 1 kg

i found the y coordinate of the center of mass of the plate it is 5/3

and i supposed it is the r

so the inertia will be mr^2

=1*(5/3)^2

=25/9

=2.77777 kg m^2

is that right??
