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]×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=[tex]3^{2}[/tex]×3.14. Now simplify and you'll get a=9×3.14, now solve and you'll get a=28.26.

Answer:28.26mm2Step-by-step explanation:I did a test with the same answer on it and I got all the questions right. I was doubting myself at first but, 100.:)
