The radius of a circle is 50 cm. Find the angle subtends by an arc of 22 cm length at the centerof the circle.

Explanation

To find the angle subtended by an arc of length 22 cm at the center of a circle with a radius of 50 cm, we can use the following steps:

### Step 1: Write down the formula for the angle subtended by an arc
The angle \( \theta \) (in radians) subtended by an arc at the center of a circle can be calculated using the formula:
\[ \theta = \frac{L}{r} \]
where \( L \) is the length of the arc and \( r \) is the radius of the circle.
