Verified Answer :

SchwarzschildRadius

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
