If you have a circle with an area of one acre, the circumference of the circle will be approximately 739.86 feet.
It is pi feet.
d = 1 foot (0.99949)
That depends on the figure. For example, for a circle, a 1:2 ellipse, and a 1:3 ellipse, you will get a different circumference for the same area.
The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.
The circumference of a circle if the diameter is 1 equals 3.1412 (π).
The circumference of a circle with a diameter of 1 is Pi: 3.1416
The formula is pi times diameter. If the diameter is 1 foot, times 3.14, the circumference will be 3.14 feet.
The circumference of any circle is (pi) x (its diameter). If diameter = 1 then Circumference = pi .
Circumference of the circle = 1 times pi in miles
If a circle has a radius of 1, the diameter is 2, and the circumference is 6.28 (approximately).
In terms of pi it is 1/3π or just 1/3π feet. If 3.1415 is assumed for pi, then the answer is 0.31831927 feet approximately.
