we all know that a circle has 360°
we all know that the circumference of a circle is 2πr
a radian is the angle which subtends an arc length equal to the radius.
So, since C=2πr, a circle has 2π radians.
So, 2π radians = 360°
1.Explain the relationship(s) among angle measure in degrees, angle measure in radians, and arc length.
