Answer:
37.68
Explanation:
The formula to solve for the circumference is C=πD. D would be diameter.
First you need to find the diameter. Diameter is the length from across the middle of the circle. You would do 2x6=12. The 6 is the radius. The radius always equals half of the diameter.
Now you do C=π12.
3.14x12=37.68=Circumference.
