    i know how to calculate the moment of inertia of an sphere with the axe in the cog

    but how do i calculate the moment of inertia of an sphere 1 m diametrus with the axe 1 m off the cog of the sphere

    something like this IO

    Take the moment of inertia of the sphere spinning on its own axis and sum it with the moment of inertia of a point mass of the same mass traveling in a circle of 1m radius.
