Find the length of a chord which is at a distance of 5 cm from the centre of a circle of radius 10 cm.

Explanation

To find the length of the chord which is at a distance of 5 cm from the center of a circle with a radius of 10 cm, we can follow these steps:

### Step 1: Understand the Geometry
We have a circle with center O and radius 10 cm. There is a chord AB in the circle, and the perpendicular distance from the center O to the chord AB is OL = 5 cm.

**Hint:** Visualize the circle and mark the center O, the chord AB, and the perpendicular distance OL.
