![]() Calculate the chord’s length if the circle’s diameter is 34 m.ĭiameter, D = 34 m. The perpendicular distance from the center of a circle to the chord is 8 m. Given radius, r = 14 cm and perpendicular distance, d = 8 cm,īy the formula, Length of chord = 2√(r 2−d 2) The radius of a circle is 14 cm, and the perpendicular distance from the chord to the center is 8 cm. Let’s work out a few examples involving the chord of a circle. If the radius and central angle of a chord are known, then the length of a chord is given by,Ĭ = the angle subtended at the center by the chordĭ = the perpendicular distance from the center of a circle to the chord.
