A chord of a circle measures 16 cm in length, and the perpendicular distance from the center of the circle to the chord is 6 cm. What is the radius of the circle?
Show answer & explanation
Correct answer: A
Explanation
Length of the chord = 16 cm
Perpendicular distance of the chord from the center = 6 cm
Chord/2 = 16/2
Chord/2 = 8 cm
r² = (Chord/2)² + Distance²
r² = 8² + 6²
= 64 + 36
= 100
r = √100 = 10 cm
