Question

The head of a nail is circular, as shown. The head of this nail has a diameter of 6 millimeters. Which measurement is closest to the area of the head of this nail in square millimeters?

Answer 1

Answer: $\boxed{\ 28.26}$

My step-by-step explanation:

1. We would use the formula πr2 (pi x radius x radius)

    2.In this problem we were given the diameter of 6, in order to find the radius, you just divide by 2

• And so we find:  6mm÷2=3mm

   3. So now that we have our radius, we can just plug the numbers into the formula.  So this would be:

• πr2= 3.14 x 3 x 3= 28.26mm2

Hope this helps you!
