The length of an arc of a circle is the product of the measure of the arc divided by 360 and the circumference of the circle.
length of AB=mAB/360 * 2π rWe are told that the measure of the desired arc is 60^(∘), the radius of the circle is 12 centimeters, and we want to find its arc length.
If we let A and B be the endpoints of our arc, we can substitute m AB= 60 and r=12 in the formula for arc length and simplify.
