Find the rotational inertia of a rod about a pivot

[Kelseywelsey]

Homework Statement

i need to find the rotational inertia of a rod about a pivot. The rod is of mass M and length L and is attached to a pivot of negligible friction located at a distance of L/3 from the left end of the rod.

Homework Equations

The Attempt at a Solution

i know that if the pivot were in the center it would be (1/12)ML and if the pivot were on the end it would be (1/3)ML, but i don't know how to find it at (L/3). can anyone help me? id really appreciate it! thanks.
