12.56 mm
The circumference of a circle is calculated using the formula C = πd, where C is the circumference and d is the diameter. Given the diameter of 4 mm, we can substitute it in the formula to find the circumference:
C = 3.14 * 4 mm
C ≈ 12.56 mm
Hence, the approximate circumference of the head of a push pin is 12.56 mm.
