WebThe arclength formula is actually derived from multiplying the portion of the circle considered (in this case, 1/2pi rad out of 2pi rad, or 90' out of 360') by 2pi(radius). From this formula (2piR times portion of circle), you get a simplified formula for arclength: S = r delta theta For a detailed explanation, see arclength from angular ...
