Gears please

[Rickey]

I need to turn a lot of gears in a machine with enormous precision. As reverence I have the diameter of the gears, ( gear1 = 12,65cm, Gear2 = 6,75 cm, etc. ). How can I use the diameter of a gear to drive the expression?

Sorry to have posted this again but there seem to be a lot of people reading this but unfortunately no answers.

How to Calculate the Circumference of a Circle

1.Find out the diameter of the circle. The diameter is the distance across the middle of a circle from one side to the other.

2.If only the radius (the distance from the center to the outside) of the circle is known, multiply it by 2 to determine the diameter.

3.Multiply the diameter by pi (3.1416) to find the circumference.

4.Alternatively, divide the diameter by 0.3183 to find the circumference.
