To find the diameter of a circle, using only the circumference, you need to divide the circumference by π, or 3.14.

So in this case, you must divide 12 by 3.14, which gives you 3.82.

I even double checked this, and should be correct then.

Answer:

The diameter is approximately 3.8 mi

Step-by-step explanation:

The circumference formula is C = πd.  Dividing both sides by π results in a formula for d (diameter) when C is known:

d = C / π

In this case, with C = 12 mi,

d = 12 mi / π, or approximately 3.8 mi
