The circumference is Pi multiplied by the diameter. In this case, the circumference is 18Pi. We can only approximate this since Pi is an irrational number. The circumference is about 56.55 inches.
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.
The circumference of a circle of 18 inches in diameter is about 56.55 inches.
A circle with a radius of 18 inches has a circumference of 113.097 inches.
The circumference of a circle with an 18-inch diameter is about 56.55 inches. (C = d x Pi)
A circle with a radius of 9 inches has a circumference of 56.55 inches and a diameter of 18 inches.
The diameter of a circle with a circumference of 18 is: 5.73
Circumference of circle: 18*pi = 56.549 inches rounded up to 3 decimal places
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).
