Find in degrees the angle subtended at the centre of a circle of diameter 50cm by an arc of length 11cm.

Explanation

To find the angle subtended at the center of a circle by an arc of length 11 cm, given that the diameter of the circle is 50 cm, we can follow these steps:

### Step-by-Step Solution:

1. **Find the Radius of the Circle:**
The diameter of the circle is given as 50 cm. The radius \( R \) can be calculated using the formula:
\[
R = \frac{d}{2} = \frac{50 \text{ cm}}{2} = 25 \text{ cm}
