A circular wire of radius `7. 5c m` is cut and bent so as to lie along the circumference of a hoop whose radius is `120c m` . Find in degrees the angle which is subtended at the centre of the hoop.

Explanation

To solve the problem step by step, we need to find the angle subtended at the center of the hoop by the circular wire. Here’s how we can do it:

### Step 1: Find the circumference of the circular wire.
The formula for the circumference \( C \) of a circle is given by:
\[ C = 2 \pi r \]
where \( r \) is the radius of the circle.
