Question

Define 1 radian write the conversion formula between radian & degree.

please explain in detail ​

Answer 1

Answer:

It follows that the magnitude in radians of one complete revolution (360 degrees) is the length of the entire circumference divided by the radius, or 2πr / r, or 2π. Thus 2π radians is equal to 360 degrees, meaning that one radian is equal to 180/π ≈ 57.295779513082320876 degrees.

Unit of: Angle

Explanation:

We define one radian, written as 1c (where the c refers to circular measure), to be the angle subtended at the centre of a unit circle by a unit arc length on the circumference.
