Moment of Inertia of a Thick-walled Cylindrical Tube Formula

Equation for calculate moment of inertia of a thick-walled cylindrical tube is,

$$I=\frac{1}{12}·m·(3·r^2+h^2)$$

where,
I = Moment of inertia of the thick-walled cylindrical tube
m = Mass of the cylinder
r = Radius of the circle of its base
h = Height of the cylinder
