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.
