If a circle has a circumference of 9, the diameter is: 2.864
If the diameter of a circle is 9 the circumference is: 28.3
A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
The circumference of 9 inch diameter circle is about 28.27 inches.
Circumference of any circle = (pi) x (diameter) Circumference of this circle = (pi) x (9 feet)
56.548667764616276 circumference = PI * diameter
The circumference of a circle is equal to Pi x diameter. So, 9 x 3.1416 = about 28.274 units.
The diameter of a circle who's circumference is 28.26 miles is: nine (9) miles
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
Doubling the radius doubles the circumference.
