Explanation:
perpendicular perpendicular axis theorem
the moment of inertia of a plane lamina about any axis is perpendicular to its plane is equal to the sum of moment of inertia of the lamina about any two mutually perpendicular axis in its plane and intersecting each other at the point where the perpendicular axis meets the lamina
parallel axis theorem
the moment of inertia of a body about any axis is equal to the sum of the moment of inertia of the body about the parallel axis passing through its centre of mass and product of its mass and the square of the distance between the axis
