The angular velocity of circular disc of radius `2cm` is `20` rad `s^(-1)`. Calculate the linear velocity of the disc.

Explanation

To find the linear velocity of a circular disc given its radius and angular velocity, we can use the relationship between linear velocity (v), angular velocity (ω), and radius (r). The formula is:

\[ v = r \cdot \omega \]

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Radius \( r = 2 \, \text{cm} \)
