You need to measure it with something flexible, like a string.If you know for sure it is a circle, it would be easier to measure the diameter, then multiply by pi.
A circle has no vertices around it
Circumference = pi*diameter or 2*pi*radius
"Diameter" is the distance all the way across the circle, through the center."Radius" is 1/2 of the diameter ... the distance from the center to the curvy part of the circle."Circumference" is the distance all the way aroundthe circle.
EDIT: To find the diameter, using the circumference - you divide the circumference by the value of Pi - Snakester1962 (Supervisor)
The diameter is 6 units.
The perimeter of a cirlcle is its circumference which is: 2*pi*radius or diameter*pi
d * pi or 2 * r * pi Where d is diameter and r is radius and pi = 3.14159
