WebExample Question Using Chord Length Formula. Question: Find the length of the chord of a circle where the radius is 7 cm and perpendicular distance from the chord to the center is 4 cm. Solution: Given radius, r = 7 cm. and distance, d = 4 cm. Chord length = 2√(r 2 −d 2) ⇒ Chord length = 2√(7 2 −4 2) ⇒ Chord length = 2√(49−16) WebArc length. A chord separates the circumference of a circle into two sections - the major arc and the minor arc. It also separates the area into two segments - the major segment and the minor segment. WebAn online arc length calculator helps to find the arc length, central angle, radius, diameter, sector area, segment height, and chord length of the circle.
