A circle with a radius of 20 cm. A chord of length 32 cm is drawn. What is the distance from the center of the circle to the chord?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 12 cm.
Circle radius OA = 20 cm
Chord length AB = 32 cm
Half chord AP = 32/2 = 16 cm
Distance from center = √(202 – 162) = √(400 – 256) = √144 = 12 cm
