What is the circumference of a circle 3ft
12pi or about 37.699
It will measure a fraction of the circle's cicumference
Divide the diameter by 2.
diameter times pi(3.14159) equals cicumference
Diameter Diameter radius
If 20 is the diameter, the circumference is 62.8 yards.
Well, I always use this formula: pi x r2
Cicumference = π*d = 56.55 units
diameter. a radius doesn't even run through a circle. a circumference is the line that surrounds the circle.
Circumference of circle when pi is 3.14: 2 times 3.14 = 6.28 units
pi=3.14 it is really long # but we shorten is to 3.14. 3.14 times the diameter
