Nothing is shown

anonymous · Answer

Lol...it is just a disc///

experimentx · Answer

find out the mass of remaining disc ... use the usual formula for moment of inertia.

anonymous · Answer

Wouldn't it depend on where the smaller circle was cut from?

anonymous · Answer

Without a diagram, are we to assume it's cut out from the center of the larger disc?
