WebChord length using perpendicular distance from the center = 2 × √ (r 2 − d 2 ). Let us see the proof and derivation of this formula. In the circle given below, radius 'r' is the … WebJan 3, 2016 · An easy solution is achieved by translating the point P to the origin (and Q, T accordingly). Then the equation of a circle by the origin is. a x + b y = x 2 + y 2. Plugging the coordinates of Q − P and T − P, you easily solve. a x q + b y q = x q 2 + y q 2 a x t + b y t = x t 2 + y t 2, and the coordinates of the center are 1 2 ( a, b) + P ...
