Question

Calculate the moment of inertia for a solid cylinder with a mass of 100g and a radius of 4.0 cm

Answer 1

Solution here,

mass of cylinder(m)=100 g

radius of cylinder(r)= 4 cm

momoent of inertia(I)=?

we have,

I=mr^2=100×4^2=1600 g/cm^2

Answer 2

Answer:

The moment of inertia for the cylinder is 1600gcm².

Explanation:

In a cylinder with mass m, in g, and radius r, in cm, the moment of inertia is given, in gcm² by the following formula:

$I = mr^{2}$

In this problem, we have that:

solid cylinder with a mass of 100g and a radius of 4.0 cm. This means that $m = 100, r = 4$.

So

$I = mr^{2} = 100*(4)^{2} = 1600$

The moment of inertia for the cylinder is 1600gcm².
