Answer:

#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

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:

#"Circumference" = 2xx6cm xx pi#
#"Circumference" = 12cmxxpi#
#"Circumference" = 37.699cm#
