Chord length of a circle

Online calculator helps to calculate the length of a chord on a circle, if its radius and the central angle it subtends are known.

The length of the chord of a circle is the distance between two points on the circle that connect it.
Formula for calculating the length of the chord of a circle: 2 * r * sin(α/2)
This formula uses trigonometric functions to determine the length of the chord based on the radius of the circle and the central angle.
