Answer:
Step-by-step explanation:
The circumference of a circle can be found with the following equation:
[tex]2*\pi*r[/tex]
Where [tex]r[/tex] is the radius of the circle.
From the given picture, [tex]r = 2[/tex], and plugging that into the equation gives us:
[tex]2\pi(2)[/tex]
[tex]4\pi[/tex]
[tex]12.57[/tex]
