Determine arc length from chord
WebThere are two basic formulas to find the length of the chord of a circle: Chord length using perpendicular distance from the center = 2 × √ (r 2 − d 2 ). Let us see the proof and … WebIf you could determine the chord length, c = AB in the diagram below then, since triangle DCB is a right triangle, Pythagoras theorem would give you. (c/2) 2 + (r - s) 2 = r 2. Solving this equation for r yields. r = (4s 2 + c …
