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
The circumference of 9 inch diameter circle is about 28.27 inches.
A circle with a radius of 9 inches has a circumference of 56.55 inches.
A circle or ellipse has a circumference. A number, such as 9, does not.
A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
If a circle has a circumference of 18pi, the radius is 9.
circumference = 2*pi*9
Circumference of any circle = (pi) x (diameter) Circumference of this circle = (pi) x (9 feet)
The circumference of a circle that is 9 cm wide is: 28.274 cm
Doubling the radius doubles the circumference.
circumference = 2*pi*9 inches
