Math 1508 name d.wilson section 4.1: radian and degree measure 1. (a) an angle is determined by rotating a ray about its endpoint. the starting po sition of the ray is the initial side of the angle, and the position after rotation is the terminal side. the endpoint of the ray is the vertex of the angle. Find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s, if the radius r =14 feet, arc length s =8 feet.
