find the radius and times it by pie 3.1415 and so on.
The circumference of a 31.4-meter diameter circle is about: 98.6 meters.
A 0.5 meter-diameter circle has a circumference of about 1.57 meters.
A circle with a radius of 1 meter has a circumference of 6.28 meters.
The circumference of a 9.5-meter diameter circle is: 29.85 meters. (C = d x Pi)
The circumference of a circle with a diameter of 18 metres is 56.5 metres, approx.
A circle 16 meters in diameter has a circumference of 16*pi or about 50.26 meters.
The diameter of a circle with a 3-meter circumference is: 0.9549 meters.
if a circle has an 18 meter diameter, then it has a 9 meter radius the circumference of a circle is 2(pi)r so the c. would be 2(pi)(9) which is 18pi. (another way to think of circumference is the diameter times pi)
3.1416 metres
it is 1254.90222
About 34.56m
Diameter of circle: 12/pi = 3.8197 meters to four decimal places
