Answer:

18.84 kilometers

Explanation:

Formula for circumference: C=2πr

1) find radius

r = d / 2

In this case the diameter is 6 so:

r = 6 / 2

r = 3

2. Plug in your values in the formula:

C = 2 (3.14) (3)

3. Solve (multiply)

C = 2 x 3.14 x 3

C = 18.84

So your answer is 18.84 kilometers, and rounded its 19 kilometers.

Hope this helps :D
