Question

Find the circumference of each circle.
1) radius = 6 m
​

Answer 1

Circumference = 37.68

Explanation:

C (circumference) = D (diameter) * pi

If the radius is 6, then the diameter is 12 because D=2r.

To find the circumference, we take the diameter and multiply it by pi. So 12*3.14=37.68
