solution

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

$C=2\pi r$

where the mathematical constant, $\pi$, has a value of approximately 3.14 and

$r$ represents the radius of the circle.

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

$\text{Circumference} = 2\times6cm\times\pi$

$\text{Circumference}=12cm\times\pi$

$\text{Circumference}=37.699cm$
