Calculate the length of the arc of a circle of radius 31.0 cm which subtands and angle of `(pi)/(6)` at the centre.

Explanation

To calculate the length of the arc of a circle given the radius and the angle subtended at the center, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Radius of the circle (r) = 31.0 cm
- Angle subtended at the center (θ) = π/6 radians
