The Arc Length of a Circle is the length of circumference of the arc.
An arc is a part of the circumference of a circle. L e n g t h th 360 2 p r The arc length formula is used to find the length of an arc of a circle. Arc length formula is used to calculate the measure of the distance along the curved line making. Where r is the radius of the circle and m is the measure of the arc or central angle in radians.
