Answer 2

Nothing is shown

Answer 3

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

Answer 4

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

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

Answer 6

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

Answer 7

gotta sleep ... good night
