since c of the pool is 18 then 2pieR = 18 /2 pieR=9 /pie R=9/pie the radius is 9/pie
Circumference of the circular pool: 20*pi feet
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
Diameter = Circumference/pi
Circumference of a circle = 2*pi*radius or diameter*pi
Circumference = 2(pi)r if diameter = 18ft then the radius is 9ft, so: Circumference = 2(pi)9 = 56.54ft =] -ray
9 feet in toward the exact center.

The circumference of a 27-foot diameter circle is about 84.82 feet. (diameter x Pi = circumference).
Six feet. Circumference = 2PiR, or Pi * Diameter. Pi is close to 3, so a pool with circumference of 18' would have a diameter of 6'
If the diameter is 25 feet then the circumference is 78.5 feet (approx).
since c of the pool is 18 then 2pieR = 18 /2 pieR=9 /pie R=9/pie the radius is 9/pie
The diameter of a pool ball is 2 and 1/4 inch diameter. The radius of a pool ball is 1 and 1/8 inches. The radius is one half of the diameter.
Circumference of any circle = 2*pi*radius or diameter*pi
the formula to start off with is the circumference is pi x diameter therefore re-arranging the formula the diameter is the circumference divided by pi diameter = circumference / pi = 18ft 8in / 3.1415 = 5ft and 11 inches to the nearest inch (to be more precice to diameter is 5ft 11.3 inches--- note it is more difficult to work in feet and inches and easier to work in metres and centimetres)
Circumference of a circle = (pi) x (diameter)C = (22) x (pi) = 69.115 feet (rounded)
