Circumference of any circle = (pi) x (diameter) Circumference of this circle = (pi) x (9 feet)

56.548667764616276 circumference = PI * diameter

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

Diameter of circle: 9/pi = 2.865 feet rounded to 3 d.p.

9*pi or 2*pi*4.5

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

Diameter of circle: 9/pi = 2.865 feet rounded to 3 d.p.

Circumference of a circle is: 2*pi*radius or pi*diameter

9*pi or 2*pi*4.5

The circumference of 9 inch diameter circle is about 28.27 inches.

The formula for the circumference of a circle is pi x diameter. Pi is usually approximated as 3.14. So 9 feet = 3.14 x diameter. Divide both sides of the equation by 3.14 and you get the diameter is approximately 2.866.

Circumference = 2(pi)r if diameter = 18ft then the radius is 9ft, so: Circumference = 2(pi)9 = 56.54ft =] -ray

You should say if the 9 feet is a radius, diameter or circumference.....if radius then 254.47 feet

Circumference of circle in inches: 108*pi = 399 inches to the nearest whole number
