Question

what is the formula of chord​

Answer 1

Answer:

Formula to Calculate Length of a Chord

Chord Length Using Perpendicular Distance from the Center Chord Length = 2 × √(r2 − d2)

Chord Length Using Trigonometry Chord Length = 2 × r × sin(c/2)

Answer 2

Answer:

The formula for the chord length is: 2rsin(theta/2) where r is the radius of the circle and theta is the angle from the centre of the circle to the two points of the chord
