Area of the circle = pi*2.52 = 19.635 square feet rounded to 3 decimal places
A circle with a radius of 5 feet has a circumference of 31.4 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)
The radius is half of the diameter so it is 2.5 Feet.
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
A circle with a radius of 5 feet has a circumference of 31.4 feet.
5ft * Pi = Approximately 15.7ft
