Finding the length of an arc using the degree of the angle subtended by the ... 6 Comments • Flag Jakob Carrica's comment ... 2 pi radians is 360 degrees, so yes, all circles have an angle of 2 pi. ..... 18π is the circumference of the circle and was given to us in the problem .... Well no because it is the length not the measure.

For example, an arc measure of 60º is one-sixth of the circle (360º), so the ... One radian is the central angle that subtends an arc length of one radius (s = r).
