3.2 Conversion between radians and degrees? Degrees to Radians: Radians to Degrees: a) 60° = b) 120° = c) 135° = d) 30º = e) 150° = f) 270° = g) 27° = h) 81° = Try the next few of questions: multiplying by 3.14159 swept through. 0° 0° = 5 x( ) e.g. 315° = a radians = ac 5*0 gives us a clearer idea of how many radians we have x 3.14159 ≈ 35 radians (1 d.p.)

So what about a complete turn? 3 2 1 1 Recall circumference of a circle= For a full circle: radians = And so the exchange rate is: radians = or = Angles in radians will often have As 180° is radians, so 90° is radians. About So one radian = degrees radius fit round a circle. degrees attached to them. radians; 45° is If you want the actual number, then simply multiply by e.g. 60° = radians. or
