(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I have attached the problem in one file and I have attached my attempt in the second file.

I only need help deriving the moment of inertia for the first (1) and fourth (4) objects but I have attached my solutions to the other objects in case it helps jog someones memory onto how to do this =p

2. Relevant equations

I = ∑m_{i}r_{i}^{2}

A = area

M = total mass

dm = change in mass

dA = change in area

dr = change in radius

3. The attempt at a solution

attempt is attached

Thank you for taking the time to read through my problem and helping me solve it, I appreciate your help
