If the circumference is 12 pi what is the diameter

Answers

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.

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
