the diameter would be 6.
Yes if the diameter is rational. But it need not be if the diameter is irrational. If the diameter is 3/pi units, for example, then the circumference will be (3/pi)*pi = 3 units.
The circumference of a circle with a diameter of 3 inches is 9.425 inches.
Since with circles the radius is half the diameter, the diameter would be 6 cm.
Divide the area by Pi to get the diameter.
