A circle with a radius of 5 feet has a circumference of 31.4 feet.
The radius is half of the diameter so it is 2.5 Feet.
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)
5.315 feet (or 5ft 3.78in)
Volume = pi*r2h = 62.8 cubic feet.
The circumference is about 15.7 feet.
pi * 5 = 15.7079633 Circumference = pi * Diameter
