The circumference of a circle is the diameter times pi (3.141) so therefore a 4 meter circumference circle has a diameter of 1.273 m E.g. 4 / 3.141 = 1.273
The circumference of a 4 foot circle is: 12.57 feet(diameter x pi = circumference).
the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi
Circumference of circle: 4 times pi in inches
12.5663706144, because the diameter (4) times Pi equals circumference
