Answer:
The circumference of the circle is
[tex]12.56[/tex]
Step-by-step explanation:
The formula to calculate the circumference of a circle is
[tex]2\pi \: r[/tex]
By looking at the image we can see that the radios is 2 km, and we are going to use pi as 3.14. So..
[tex]formula \: = \: 2\pi \: r \\ 2(3.14)(2) = 6.28 \times 2 \\ = 12.56km[/tex]
