8 pi; taking pi as 3.14 then answer is 25.12
25.13 meters
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.
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
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
The circumference of a circle with a diameter of 25 is: 78.54
If the diameter of a circle is 9 the circumference is: 28.3
If a circle has a diameter of 14, the circumference is: 43.98.
If a circle has a diameter of 2.25, the circumference is: 7.069
