A circle with circumference 12 has an arc with a 330° central angle.

Answer:
arc length =11
Step-by-step explanation:
To find the arc length , we take pi *2 r and multiply by the fraction of the circle
The circumference is 12 which is equal to 2 * pi *r
arc length = 12 * 330/360
arc length = 12 * 11/12
arc length =11
