Question

Points A and B lie on a circle with radius 1, and arc AB has a length of
$\frac{\pi}{3}$. What fraction of the circumference of the circle is the length of arc AB ?​

Answer 1

Answer:

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. The fraction 1/6 can also be rewritten as 0.166 or 0.167. 1/6, 0.166, or 0.167.
