Circumference is 2x pi x r or just pi x d. If the diameter d = 11km, then the circumference would be 11km x pi
That is usually a good enough answer, but you could also approximate pi as 3.14159, in which case the answer would be 34.55749 km.

Multiply the diameter by pi to find the circumference
To find the radius of the wheel, we first calculate the circumference of the wheel using the formula: Circumference = 2 * π * radius. Since the wheel travels a distance of 11 km in 5000 revolutions, each revolution covers a distance of 11 km / 5000 = 0.0022 km. The circumference of the wheel is twice the distance covered in one revolution. Thus, we have Circumference = 2 * 0.0022 km = 0.0044 km. By setting up the equation 0.0044 km = 2 * π * radius, we can solve for the radius as 0.0044 km / (2 * π) ≈ 0.0007 km, or 0.7 meters.
11 kilometers=11,000 meters
11 000 m = 11 kmTo convert from m to km, divide by 1000.
If 11.6 km is diameter, then 11.6 * pi = 36.4425 km circumference If 11.6 km is radius, then 11.6 * 2 * pi = 72.8850 km circumference
The circumference of a circle with a diameter of 16 km is: 50.3 km
A circle with a radius of 1.8 km has a circumference of 11.31 km
A circle with a radius of 126 km has a circumference of 791.68 km.
1 km = 1,000 metres; thus, 11 km = 11,000 metres.
Circumference = pi*2.5 = 7.85 km
Circumference of circle: 2*pi*13.1 = 82.30972752 km
