Length of an Arc

A circle of radius 120 m is divided into 8 equal sectors. Find the length of the arc of each of the sectors

Two gates are fitted at the entrance of a library. To open the gates easily, a wheel is fixed at 6 feet distance from the wall to which the gate is fixed. If one of the gates is opened to 90°, find the distance moved by the wheel (π = 3.14)
