The Circumference (C) of a circle will ALWAYS be 3.1415926 times its Diameter (D).
This irrational number (which goes on forever) is called "pi".
C = pi x D
This will work for any circle, because as the circle gets bigger or smaller, so does the circumference by the same scale.

If the diameter of the circle is 69mm then what is the circumference of this circle?
To find the circumference of a circle, you can use the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. Given that the diameter of the circle is 69mm, you can substitute this value into the formula: C = π * 69mm ≈ 216.769mm. Therefore, the circumference of the circle is approximately 216.769mm.
