# Moment of inertia of a rotating black hole [duplicate]

The moment of inertia of a massive object about a given axis describes how its mass is distributed about that axis. I understand that a rotating black hole of a given mass and angular velocity possesses angular momentum, and one would think that it therefore possesses a certain moment of inertia about its axis of rotation. My question is this: can knowledge of that moment of inertia tell us anything about how the black hole's mass is distributed about its axis of rotation?
