just over 56½ inches (18 pi)
The circumference of a circle is calculated using the formula ( C = \pi d ), where ( d ) is the diameter. For an 18-inch diameter, the circumference is approximately ( C = \pi \times 18 \approx 56.55 ) inches. Rounded to the nearest inch, the circumference is 57 inches.
Circumference of a circle: 2*pi*radius or diameter*pi
If the radius is 18 feet - then the diameter is 36 feet. The circumference measurement is irrelevant !
(pie)(diameter)=(circumference) (pie)(9)(2)=18(pie)=56.549

The circumference of a circle with an 18-inch diameter is about 56.55 inches. (C = d x Pi)
The formula for circumference is pi*d = circumference. Therefore just divide the circumference by pi to get diameter. Approx. answer = 5.73
