A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
Circumference of any circle = (pi) x (diameter) Circumference of this circle = (pi) x (9 feet)
Circumference of a circle is: 2*pi*radius or pi*diameter
56.548667764616276 circumference = PI * diameter
9*pi or 2*pi*4.5
The circumference of a 9 circle is: 28.3
Circumference of circle in inches: 108*pi = 399 inches to the nearest whole number
Diameter of circle: 9/pi = 2.865 feet rounded to 3 d.p.
You should say if the 9 feet is a radius, diameter or circumference.....if radius then 254.47 feet
If the diameter of a circle is 9 the circumference is: 28.3
If a circle has a circumference of 9, the diameter is: 2.864
Circumference = 2(pi)r if diameter = 18ft then the radius is 9ft, so: Circumference = 2(pi)9 = 56.54ft =] -ray
