Correct option is C. Radian measure of 7π³ = 420 degrees
What is Radian?
Firstly, the radian is a unit for measuring the angles that we mainly use in the trigonometry. We use it instead of the degrees. Whereas a full sphere or a circle is of 360 degrees, a full sphere or a circle is just above six radians.
The radian is most usually represents itself by the symbol rad. Its alternative symbol is C.
- The full angle is 2 pie radians and therefore it is 360 degree.
- A right angle is pie/2 radians.
- A straight angle is pie radians.
1 radian = (180π)°
Step 1 : To convert radians to degrees, multiply the given radian by 180/pi
7 pi/3 x 180/pi
Step 2 : Cancel pi
7/3 x 180
= 420 degrees
