Moment of inertia of a disc about it's center perpendicular to the plane of the disc is 
& Moment of inertia of a disc about one of its diameter is 
Now both dices have same surface mass density 
say 
then mass of 
discs with radius 
M.I of disc 1 about center, 
to the plane 
mass of 2nd disc with radius 
M.I of 2nd disc about one of it's diameters is
