Answer:
9pi approx= 28.3sqmm
Explanation:
The question says the diameter is 6mm. So the radius is 3mm. They are asking for the area. It says area of the nail. But since no other measurements are given it must mean, area of the nailhead.
Area of a circle is pi×r^2
=pi(3^2)
=9pi
This is the exact answer. 9pi sqmm
or if they want a decimal approximation it is 28.3 sqmm
