Answer 1

Answer:

A complete angle of a circle is 360 degrees of 2π radians. This is the basis for converting the measures of angles from one unit to another. That means a circle subtends an angle whose radian measure is 2π and its degree measure is 360° at the centre. This can be written as:

2π radian = 360°( or)  π radian = 180°

The above relationship allows us to formulate a radian measure in degree measure and a degree measure in radian measure. We know that the approximate value of pi (π) is 22/7. By substituting this value in the above relation, we get;

1 radian = 180°/π = 57° 16′ (approx)

Also,

1° = π/80 radian = 0.01746 radian (approx)
