The length of an arc of a circle is obtained by using the formula L=?r?/180, where L is the length of the minor arc of the circle, r is the radius of the circle and ? is the angle made by the arc at the center of the circle.
Continue ReadingA circle has three different types of arcs. The length of the semicircular arc is obtained by using the formula ?r, and the length of the major arc of a circle is obtained by subtracting the length of minor arc of the circle from the circumference of the circle. Thus, the length of the major arc of a circle is given by the formula 2?r - ?r?/180.
