# A circle has a diameter of 12 meters. What is the circumference of the circle?

May 22, 2017

The circumference of the circle is $37.6991118430 \text{Meters}$

#### Explanation:

For this explanation, we will sat that:

$\text{Diameter}$ is $D$, $\text{Radius}$ is $R$ and $\text{Circumfrence}$ is $C$.

The formula to find the circumference of a circle is

$C = 2 \pi R$

or

$C = \pi D$

In this case, we know what the Diameter of the circle is, $12 \text{meters}$, so we will substitute $12$ in the second formula.

$C = \pi D$

$C = \pi 12$

$C = 3.1415926536 \times 12$
