Calculate the moment of inertia of a disc about its any diameter ?

Explanation

To calculate the moment of inertia of a disc about its diameter, we can follow these steps:

### Step 1: Understand the Moment of Inertia of a Disc
The moment of inertia (I) of a disc about an axis perpendicular to its plane and passing through its center (the center of mass) is given by the formula:
\[ I_{CM} = \frac{1}{2} m r^2 \]
where \( m \) is the mass of the disc and \( r \) is its radius.
