The circumference of the circle is #37.6991118430"Meters"#

For this explanation, we will sat that:

#"Diameter"# is #D#, #"Radius"# is #R# and #"Circumfrence"# is #C#.

The formula to find the circumference of a circle is

#C = 2piR#

or

#C = piD#

In this case, we know what the Diameter of the circle is, #12"meters"#, so we will substitute #12# in the second formula.

#C = piD#

#C = pi12#

#C = 3.1415926536 xx 12#

#color(blue)(C = 37.6991118430#
