A chord of length 24 cm lies 7 cm away from the center of a circle. What is the approximate radius of the circle?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 14 cm.
Half chord AP = 24/2 = 12 cm
Here, OP ⊥ AP
Radius = √[(AP)2 + (OP)2]
= √(122 + 72)
= √(144 + 49)
= √193
≈ 14 cm
