The diameter of a circle with a 12-foot circumference is about 3.82 feet. (circumference divided by Pi = diameter).
The circumference of a circle with a diameter of 12 is about: 37.7 (C = diameter x Pi).
The circumference of a circle with a diameter of 12 cm is: about 37.7 cm
The circumference of a circle is pi times the diameter, so it would be 12*pi or about 37.7.
If a circle has a diameter of 12 inches the circumference will be about 37.7 inches. (C = d x Pi)
