The circumference of a circle is calculated using the formula 2πr, where r is the radius of the circle.

Step 1: Identify the radius of the circle. In this case, the radius is given as 2 millimetres.

Step 2: Substitute the radius into the formula. This gives us 2π(2) = 4π.

Step 3: Calculate the value. The value of π is approximately 3.14159. So, 4π is approximately 4 * 3.14159 = 12.56636.

So, the circumference of the circle is approximately 12.56636 millimetres.
