Question

5. The head of a nail is circular, as shown. The head of this nail has a diameter of 6 millimeters.

What is the approximate measurement of the area of the head of the nail in square millimeters (mm2)? Use 3.14 to approximate π, do not round your answer.


Please show your work!!!

Answer 1

28.26mm2

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.:)

Answer 2

28.26
`mm^(2)`

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.
