The formula for the circumference of a circle is C = 𝜋d, where d is the diameter.
Circumference = 𝜋 x diameter
Circumference = 3.14 x 18mm
Circumference = 56.52mm
Therefore, the circumference of the circle is 56.52 millimeters.
The diameter of a circle is 18 millimeters. What is the circle's circumference?
