28.26 $mm^{2}$

Step-by-step explanation:

The head of a nail would be considered a circle, therefore you would want to use the formula for area of a circle: a= $r^{2}$ ×π but in this circumstance using π as 3.14.

Because we are given diameter we need to DIVIDE by 2 to get your radius. 6/2=3. Your radius is therefore 3 and can be plugged in to you equation as a= $3^{2}$ ×3.14. Now simplify and you'll get a=9×3.14, now solve and you'll get a=28.26.
