Moment of inertia, Physics

Calculate the moment of inertia of An 8.00-kg cylinder, of length 19.5cm and diameter 12.0 cm,about the central axis of the cylinder,if the cylinder is (1) thin-walled and hollow, and (2)solid.

Ans) The moment of inertia of a body doesn''t change if we don''t change the distance of particles from axis. So, moment of inertia of a cylinder about central axis is same as moment intertia about same axis of a disc/ring(if hollow).

For ring,

I=Mr2

For disc,

I=(Mr2)/2

 You can put the values.
