Question

In a circle,the length of chord is 16 and its distance from the centre is 15.Find the diameter of the circle.

Answer 1

Heya User,

Length of chord = 16 units
Altitude from center to chord = 15 units

--> Perpendicular to Chord from center bisects the chord

=> Length of bisection = 8 units
=> Length of Altitude = 15 units

Apply Pythagoras, Radius² = 15² + 8² = 17²

=> Radius = 17units √√
