The angle subtended by a chord AB on the circumference of a circle is 90°. If the length of chord AB is 16 cm, then what will be the radius of this circle?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 8 cm.
If an angle subtended by a chord on the circumference of a circle is 90°, then the chord is the circle's diameter.
Diameter = AB = 16 cm
Radius = 16/2 = 8 cm
