It is not clear whether the circumference is 9 feet and you want the radius or diameter, or you have either the radius or diameter - which is 9 ft - and you want the circumference. The formulas are Circumference = 2*pi*r = 2*pi*d where r is the radius, d the diameter, and pi is the mathematical constant approximated by 3.14159

If a circle has a circumference of 9, the diameter is: 2.864

A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).

Since Circumference = 2πr if the circumference is 9π r = 9π/2π = 9/2 = 4.5

r2*pie=circumference 9(9)*pie 81*pie 254
