Assume you mean the chord of a circle? If the angle between the two radii from the ends of the chord is A, and the radius of the circle is R, the chord length L will be
L = 2RsinA/2. You can prove this easily by joining the point bisecting the chord to the centre, you then have two rightangled triangles, with an included angle of A/2, and an opposite side of L/2. So sinA/2 = L/2R.

How do you find the chord length when radius is given?
To find the chord length when the radius is given, you can use the formula: ( L = 2 \times r \times \sin\left(\frac{\theta}{2}\right) ), where ( L ) is the chord length, ( r ) is the radius, and ( \theta ) is the central angle in radians subtended by the chord at the center of the circle. If the angle is not provided, you can also use the relationship involving the distance from the center to the chord (perpendicular distance) to find the chord length.
