The circumference of a circle with a diameter of 18 inches is 56.5 inches.
A circle with a radius of 18 inches has a circumference of 113.097 inches.
Diameters don't have "circumference." If you want the circumference of a circle with diameter 18 in, then it is just pi*d = 18pi inches.
Circumference = 2 x pi x radius = pi x diameter where pi = 3.1416 Diameter = circumference / pi = 36/3.1416 = 11.46
All depends what you mean by 18 inches, is that the circumference, the diameter or the radius
The circumference of a circle with a diameter of 18 inches is 56.5 inches.
The circumference of a circle that has a diameter of 18 inches is about 56.55 inches. (C = d x Pi).
An 18" diameter circle has a circumference of about 56.5 inches.

Diameters don't have "circumference." If you want the circumference of a circle with diameter 18 in, then it is just pi*d = 18pi inches.
The distance around a circle is called the circumference. The formula for the circumference of a circle is C = πd, where C is the circumference, d is the diameter, and π is approximately 3.14159. For a circle with a diameter of 18 inches, the circumference would be C = π(18) = 56.5487 inches.
The circumference of a circle with a diameter of 18 yards is: 56.55 yards (diameter x Pi = circumference).
