$37.699 c m$ $37.699cm$

Explanation:

The circumference of a circle can be obtained by using the equation below:

![http://www.wikihow.com/Calculate-the-Circumference-of-a-Circle]( useruploads.socratic.org )

where the mathematical constant, $π$ $pi$ , has a value of approximately 3.14 and $r$ $r$ represents the radius of the circle.

All we have to do is multiply the given radius by two and multiply that value by $π$ $pi$ to determine C:

$Circumference = 2 \times 6 c m \times π$ $"Circumference" = 2xx6cm xx pi$
$Circumference = 12 c m \times π$ $"Circumference" = 12cmxxpi$
$Circumference = 37.699 c m$ $"Circumference" = 37.699cm$
