Points A and B lie on a circle with radius 1, and arc
⌢
AB
has a length of
π
3
. What fraction of the circumference of the circle is the length of arc
⌢
AB
?

Answer: To figure out the answer to this question, you'll first need to know the formula for finding the circumference of a circle. The circumference, C, of a circle is C=2πr, where r is the radius of the circle. For the given circle with a radius of 1, the circumference is C=2(π)(1), or C=2π. To find what fraction of the circumference the length of ⌢ AB is, divide the length of the arc by the circumference, which gives π 3 ÷2π. This division can be represented by π 3 * 1 2 π= 1 6 . The fraction 1 6 can also be rewritten as 0.166 or 0.167.

The final answer is 1 6 , 0.166, or 0.167.
