## hollow cylinder inertia

#### Moment of Inertia of Hollow Sphere VEDANTU

Moment of Inertia of a Hollow Sphere The moment of inertia of a hollow sphere otherwise called a spherical shell is determined often by the formula that is given below I = MR 2 Let s calculate the moment of inertia of a hollow sphere with a radius of m a mass of kg Now to solve this we need to use the formula which is; I = MR 2 Substituting the values we get I =
