Answer:

28.26[tex]mm^{2}[/tex]

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=[tex]r^{2}[/tex]Γ—Ο€ but in this circumstance using Ο€ 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=[tex]3^{2}[/tex]Γ—3.14. Now simplify and you'll get a=9Γ—3.14, now solve and you'll get a=28.26.

Answer:

28.26mm2
