# Mass moment of inertia of a thick spherical shell

Calculates the mass moment of inertia of a thick spherical shell about its central axis.

`I = 2/5*m*(R^5-r^5)/(R^3-r^3)`**Enter 'x' in the field to be calculated.**

We use the following formula to calculate the mass moment of inertia of a thick spherical shell about its central axis.

`I = 2/5*m*(R^5-r^5)/(R^3-r^3)`

m : mass of sphere (kg)

R : radius of the spherical shell (outer radius) in meter (m)

r : radius of the cavity (inner radius) in meter (m)
