1. The problem statement, all variables and given/known data

Hi I have to calculate the moment of inertia for a thick-walled T profile

2. Relevant equations

3. The attempt at a solution

I have determined the center of gravity (the easy part) of it already how should I proceed?

Thanks Pep

$$I_G=\int r^2 dm$$. You should find what dm is worth in your case.
