WebbIn any circle of radius r, the ratio of the arc length to the circumference equals the ratio of the angle Theta - Simple English Wikipedia, the free encyclopedia subtended by the arc at the centre and the angle in one revolution. Thus, measuring the angles in radians, 2r=2 =r. Webbonly III is true. ] Q.5 A and B are points on the circumference of a circle of radius r and centre O. If the distance between A and B is r, find the measure of angle AOB in radian.
