The question on the image seems to be related to a circle with a chord \( PQ \) and a radius \( OR \) perpendicular to the chord. The problem states:

- \( OR \) is the perpendicular from the center \( O \) to the chord \( PQ \), and its length is \( 8 \, \text{cm} \).
- The radius of the circle is \( 10 \, \text{cm} \).

You are asked to find the length of the chord \( PQ \).

### Solution:
This is a typical geometry problem involving a circle, a radius, and a perpendicular from the center to a chord. When a radius is drawn perpendicular to a chord, it bisects the chord. Therefore, \( OR \) is the perpendicular distance from the center \( O \) to the chord, and the length of \( PQ \) can be found using the Pythagorean theorem.

Let:
- \( O \) be the center of the circle,
- \( OR = 8 \, \text{cm} \),
- The radius \( OQ = 10 \, \text{cm} \) (since \( OQ \) is a radius of the circle),
- \( P \) and \( Q \) are the points where the chord intersects the circle.

Now, let \( PR \) be half the length of the chord \( PQ \
