The mass of a uniform circular ring of radius `0.2m` is `0.1kg`. Calculate the moment of inertia of the ring about an axis passing through its center and perpendicular to its surface.

Explanation

To calculate the moment of inertia of a uniform circular ring about an axis passing through its center and perpendicular to its surface, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Formula**:
The moment of inertia \( I \) of a ring about an axis through its center and perpendicular to its plane is given by the formula:
\[
I = m r^2
