WebQuestion: Find the length of the chord of a circle where the radius is 7 cm and perpendicular distance from the chord to the center is 4 cm. Solution: Given radius, r = 7 cm and distance, d = 4 cm Chord length = 2√ (r 2 −d 2) ⇒ Chord length = 2√ (7 2 −4 2) ⇒ Chord length = 2√ (49−16) ⇒ Chord length = 2√33 ⇒ Chord length = 2×5.744
