Question

A circle with a circumference of 6 has an arc with a 20 degree central angle.

What is the arc length?

Answer 1

1/3

Explanation:

If the central angle is 20 degrees, that means that the arc of this circle takes up 1/18 of the circle's circumference. Because there are 360 degrees in a circle, we get 1/18 by dividing the part (20 degrees) over the whole (360 degrees)

Now that we know that, we do the same for the circumference measure by taking 1/18 of 6, which is 1/3
