Hello.
I'm having trouble with Moments of Inertia of Various Bodies.

The problem is:

A thin 3.90-kg rod of length 80.0cm , about an axis parallel to the rod and passing through it.

I know how to do the problem so long as it's on the table provided for us, but this one doesn't seem to match any of the cases that they have provided for us. Should I be putting some cases together? If so, which ones and how?

I also have these:

a) An 5.50-kg cylinder, of length 22.0cm and diameter 30.0cm , about the central axis of the cylinder, if the cylinder is thin-walled and hollow.
