You neglected to say whether the 4mm is the radius of the circle, or the diameter,or the circumference. Each possibility gives you a different area.
The volume of a right circular cone with a radius of 4mm and a height of 6mm equals 140.88mm3

4mm is 0.15748032 of an inch.
7mm x 4mm = 28mm squared = Area // (7+7)+(4+4) = 22mm = Perimeter

Pie (3.14159...) times (*) 2 times (*) radius === or This equation may be for the area but hopefully it's for circumference. Anyway, the answer to your question is 25.13274123... (Pie times 2 times 4mm).
A circle with a diameter of 4 mm has an area of : 12.57 mm2
h = 5.9949 m
Circumference = Pi (3.14) times Diameter (C=pD) Diameter = 2 times the Radius (D=2R) or Circumference divided by Pi Area = Pi times the radius squared (A=pr2) So, 4 / 3.14 = 1.27. The diameter of a 4mm nail is 1.27mm.
