Moment of inertia

Question

A cylinder with a radius of 1.33 m

has a moment of inertia of

272 kg-m². What is its mass?

can someone Plzz thourghly answer this ?!

Answer 1

So the general formula for the moment of inertia is I = m*r²,

where I is inertia, m is mass, and r is the distance from the axis of the rotation.

So now we substitute the values provided into the formula,

272 = m*(1.33)²

Solving for m, we find the mass to be about 153.77 kg.
