Greetings and Happy Holidays!

The formula for the circunference of a circle is:
[tex]C=2 \pi r[/tex]

Input
the value for the radius.
[tex]C=2 \pi(6)[/tex]

Multiply.
[tex]C=12 \pi[/tex]

...or if you require a fully simplified answer:
[tex]C=37.699[/tex]

The Answer Is:
[tex] \left[\begin{array}{ccc}C=12 \pi \end{array}\right] [/tex]

I hope this helped!
