# My First Brilliant Problem!

A uniform disk of radius $$R$$ and mass $$M$$ has a hole of diameter $$R$$ drilled out from it. The hole that is drilled out spans from the center of the disk to the edge of the disk.

$$R = 10 \text{ meters}, M = 5 \text{ kilograms}$$

The axis of rotation is through the center of the disk. What is the moment of inertia of the disk with the hole drilled out? Answer in $$\text{kg m}^2$$.
