To find the circumference of a circle, you can use the formula:
Circumference = π × diameter
In this case, we are provided with the diameter of the circle, which is 8 mm, and we are using 3.14 for π. Plugging the values into the formula gives us:
Circumference = 3.14 × 8 mm
Circumference = 25.12 mm
Therefore, the circumference of the circle with an 8 mm diameter is 25.12 mm.
