What is the length of arc AB?
Space & Navigation10π5/18 of the circumference of the circle, which equals 2πr, according to the formula for circumference. length of arc AB = (5/18)(2πr) = (5/18)(2π(18)) = 10π. Thus, the length of arc AB is 10π. How do you find the length of arc AB? How do you calculate arc length without the angle? Divide the chord
