Answer:
0.167
EXPLANATION:
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
÷
.
This division can be represented by
×

can also be rewritten as 0.166 or 0.167.
