You neglected to say whether the 4mm is the radius of the circle, or the diameter,or the circumference. Each possibility leads to a different area.
2x(3x5+3x4+4x5) = 94 sq mm
50.265 square mm
A circle with a diameter of 4 mm has an area of : 12.57 mm2
A 4mm diamond measures 4mm in at least one measurement.
1st, it is not a cube, all sides of a cube are equal. 2nd rectangular solids, A = 2lw + 2lh+ 2wh 2x1.5x4 + 2x1.5x10.5 + 2x 1.5x10.5 = 127.5 square mm
4mm is 0.15748032 of an inch.
As wide as 4mm on a ruler
