8 pi; taking pi as 3.14 then answer is 25.12
25.13 meters
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
The circumference is pi times twice the radius, and the diameter is twice the radius, so the circumference is pi times the diameter: 25.13278 feet.
Divide the circumference (38") by Pi (about 3.1416) to get the diameter in inches.
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
If you divide eight by pi, you get 2.54647909 as the diameter. If you divide eight by 3.14 (simplified pi), you get 2.54777070 as the diameter.
A circle with a circumference of 11.25 has a diameter of: 3.581
If the diameter of a circle is 9 the circumference is: 28.3
If a circle has a diameter of 5 the circumference is: 31.4
The circumference of a circle that has the diameter of 8 is: 25.1
The diameter of a circle with the circumference of 3.25 is: 1.034
