The length of a tangent from a point A at distance 5 cm from the centre of the circle is 4 cm. Find the radius of the circle.

Explanation

To find the radius of the circle given the length of the tangent and the distance from the center of the circle to the point from which the tangent is drawn, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Information**:
- Distance from point A to the center O of the circle (OA) = 5 cm
- Length of the tangent from point A to point B (AB) = 4 cm
