Best Answer

Circumference = 2(pi)r

if diameter = 18ft then the radius is 9ft, so:

Circumference = 2(pi)9 = 56.54ft

The circumference of a circle is determined by multiplying the diameter (d) by the number pi. Therefore, the circumference of a circle with a diameter (d) of 18 feet is 18pi or 18x3.14159265358979323846... Roughly 56.54866776461627829228.

56.548667764616276 circumference = PI * diameter

d = 5.73 feet.

Diameter = 56.52/pi = 17.99087477 or about 18 feet

The circumference of a circle with a diameter of 18 inches is 56.5 inches.
