WebThe radian is just another way of measuring the size of an angle. For instance, to convert angles from degrees to radians, multiply the angle (in degrees) by π/180. Similarly, to convert radians to degrees, multiply the angle (in radians) by 180/π. Example 5. Find the length of an arc whose radius is 10 cm and the angle subtended is 0.349 ... WebYou would say 120 degrees is 1/3 of 360 degrees because 120/360 is 1/3. Fractions take the form (part of a whole) / (whole). Here, 2 radians is the part of the whole, and 2 pi radians is the whole. So, you end up with (2 radians) / (2 pi radians), and the 2 and the radians cancel out, leaving you with 1/pi of a circle.
