The circumference of a circle is NOT 360 degrees. The circumference is the distance around the curve of the circle. This has a measurement unit of length, not degrees. The angular displacement, in going completely around any point is 360 degrees and that follows from the definition of a degree.

It has been DEFINED that way, many centuries ago. You can divide the circle into as many parts as you want, but in the past, people seemed to like multiples of 12.A much more natural unit for angles is the radian. In that case, the circumference is equal to 2 x pi. It turns out that many formulae are simpler when angles are expressed in radians.

What is the circumference of a circle whose arc length is 19.68 and degrees is 94?

The circumference will have 360 degrees. So the arc is 94/360 of the whole circle. That is, the whole circle will be 360/94 of the arc length. So the circumference of the shole circle is 19.68*360/94 = 75.37 units (to 2 dp)
