well, since the equation for circumference is
$2 \pi r^(2)$ and the diameter is double the radius, the diameter will end up being about 3.82

So,

The formula for the circumference of a circle:

$C = 2 \pi r\ or\ C = \pi D (diameter)$

We can now substitute the given values and solve for D.

$12 \pi = \pi D$

Divide both sides by pi.

12 = D

The diameter of the circle is 12 units.

If the circumference is 12 pi what is the diameter
