The smallest commercially (easily) available steel rod is about 0.014" diameter.
If the steel rod has a circular cross-section - the usual case - you can use the formula for a cylinder. Since the area of the base is quite small, it can be ignored - just calculate length x diameter x pi.
No. The formula for circumference of a circle is pi x diameter. As pi is 3.14... then the circumference will be at least 3.14 times the diameter.
You cannot. All that can be said is that the diameter is at least 6 inches in length.
OD is Outside Diameter - at least when you are talking about pipe...
No. The diameter of Sirius A is about 1.7 times that of the sun. To be considered a supergiant a star must be at least 100 times the diameter of the sun.
Azotobacter's cells are large rods, at least 2 microns in diameter
The diameter of our pumpkins increased steadily all summer until we harvested them in the fall. A tennis ball has a much smaller diameter than a basketball. The rod needs to have at least a one inch diameter for the curtains to hang properly.
Make at least one mistake in your calculation.
large diameter wire simply because it will move easier Technically they would have the same resistance, but the larger diameter wire would allow more current to flow as it would have more room to move.

Nobody makes a bullet that small. The smallest bullets are at least 4mm in diameter.
Water droplets at least 0.5 millimeters in diameter are considered raindrops. These larger raindrops typically form in more intense rain showers or storms, as they have had more time to grow in size by merging with other droplets.
