You neglected to say whether the 4mm is the radius of the circle, or the diameter,
or the circumference. Each possibility gives you a different area.
Well, darling, the circumference of a circle is calculated using the formula C = 2Ļr, where r is the radius. Plug in the radius of 4 mm, and you get a circumference of 8Ļ mm, or approximately 25.13 mm. So, there you have it, sugar, the circumference of a circle with a radius of 4 mm.
Diameter of circle: 13/pi = 4 mm rounded to the nearest integer
The circumference of a circle with a diameter of 13 mm is: 40.84 mm
The circumference of a circle that is 16 mm in diameter is 50.27 mm
If the circle's circumference is 58 mm then its diameter is 58/pi which is about 18.462 mm

A 4 mm circle would have a diameter of 4 millimeters, meaning the distance across the circle passing through its center would be 4 mm. This circle would be relatively small, about the size of a standard pencil eraser. In terms of area, the circle would cover approximately 12.57 square millimeters.
