Chord and central angle The height of the arc and the angle subtended by the arc (not shown in figure) are also calculated. To get the height of the arc, I subtracted the wall height from the peak height, Using the Pythagorean theorem, I was able to solve for the radius of the arc. Chord Length when radius and angle are given is the length of a line segment connecting any two points on the circumference of a circle with a given value for radius and angle and is represented as l=sin(∠A/2)*2*r or Chord Length=sin(Angle A/2)*2*Radius.Radius is a radial line from the focus to any point of a curve and The angle A is one of the angles of a triangle. This defines the arc. Let the radius of the circle be r; Let the height and width of the arc be h & d; Now, the diameter DC bisects the chord AB in two halves, each having length d/2 Hi Wayne, I don't have a nice answer to your question but I'll show you what I can do.
