Find Arc Length and Radians Equations of Circles Review

The figure shows the ideal pattern of movement of a herd of cattle, with the arrows showing the movement of the handler as he moves the herd. The arc the handler makes from the starting point to the return point should be a quarter of a circle. Based on this theory, what distance will the handler move from the starting point to the return point if he creates an arc of a circle of radius 80 feet?
