$C=12pi$ in

$C=2pir.$ Given $r=6$ ,

$C=2pi(6)=12pi$ in

$12pi$ inches or about $37.699$ inches

Here's how I did it:

The formula for the circumference of a circle is $2pir$ .

We know that the radius is $6$ inches, so we can plug that into the formula:
$2pi(6)$

Now multiply the $2$ with the $6$ :
$12pi$ inches or about $37.699$ inches (when we multiply the $12$ with $pi$ )

Hope this helps!
