Question
**Question:** Find the length of \( \overline{AB} \) in circle \( O \). **Diagram Description:** The image shows a circle with center \( O \). There is a segment \( AB \) that is a chord of the circle. The distance from the center \( O \) to the chord \( AB \) (perpendicular to \( AB \)) is given as 21 cm. A right-angle marker is shown at the point of intersection of the perpendicular distance from \( O \) to \( AB \). **Explanation:** 1. \( O \) is the center of the circle. 2. The perpendicular from \( O \) to \( AB \) is given as 21 cm. 3. \( AB \) is a chord of the circle. The task is to determine the length of the chord \( AB \).
