Moment of Inertia (not through symmetry axis)

[sterling32157]

Homework Statement

What is the moment of inertia of a solid cylinder (of mass 8.41kg and radius 7.5cm) rotating about an axis parallel to the symmetry axis but passing through the edge of the cylinder?

Homework Equations

I=.5mr²,
but how does this change when the axis is passing through the edge of the cylinder?

The Attempt at a Solution

I can't attempt it intelligently until I have the correct equation. Once I do, I can finish it off myself.

You will need the parallel axis theorem:

I=I_center+mr²
