Answer 1

plz be clear and complete the question so that we can help

Answer 2

Answer:

The moment of inertia of solid cylinder is 0.4 kg-m².

Explanation:

Given that,

Mass of solid cylinder = 20 kg

Length = 1 m

Radius = 0.2 m

Suppose we find the moment of inertia of the solid cylinder

We need to calculate the moment of inertia of the solid cylinder

Using formula of moment of inertia

$I=\dfrac{1}{2}MR^2$

Put the value into the formula

$I=\dfrac{1}{2}\times20\times(0.2)^2$

$I=0.4\ kg-m^2$

Hence, The moment of inertia of solid cylinder is 0.4 kg-m².
