9/18/2023 0 Comments Chord geometry problemsThe length of a chord, given the radius and central angle.In the above illustration, the length of chord PQ = 2√ (r 2 – d 2) Where r = the radius of a circle and d = the perpendicular distance from the center of a circle to the chord. If the length of the radius and distance between the center and chord is known, then the formula to find the length of the chord is given by, The length of a chord, given the radius and distance to the center of a circle.Each formula is used depending on the information provided. There are two formulas to find the length of a chord. For example, chord AB is equal to chord CD if PQ = QR.
