C = 2pi*r
the radius is half of diameter
r = 12/2
r = 6
C = 2*3.14*6
C = 37.68m
hope this helps

Circumference = 2 x pi x radius = pi x diameter
Circumference = 3.14 x 12 m
= 37.68 m

Circumference of a circle is equal to pi times the diameter.
What's so hard about that, you have both numbers.

C=d x pi=n or C=r x 2 x pi=n
3.14
x 12
____
37.68
so C= 37.68

circumference = diameter*pi
=12*3,14=37.68

Confirming it is 37.68
circumference = 2 * pi * R
R=6m if diameter is 12m

c = d*pi.
So multiply pi * your diameter of 12m.
