## Circumference Calculator usage instructions.

Launch the Circumference Calculator as a mobile app or online on your computer.

Indicate in the relevant field the circle's radius or diameter. While some calculators may compute the diameter automatically based on the radius input, others may have distinct sections for radius and diameter.

.

The "Calculate" or "Find Circumference" buttons can be tapped or clicked to initiate the computation.

You can use the calculator to find the diameter of a circle in inches, centimeters, or meters, depending on the unit of measurement you choose.

To calculate the circumference of a circle, one can use the following formula:

The formula for the circumference of a circle is given by **C = πr.**

The circle's radius is represented by the variable r, its circumference is represented by the variable C, and the mathematical constant π (pi) is approximately equal to 3.14.

**For instance**

Suppose you are interested in determining the diameter of a circle with a radius of five centimeters. The value of the radius would be added to the computation shown above.

The formula for the circumference of a circle is C = 2r. Using this formula, we can calculate the circumference of a circle with a radius of 10 cm. By substituting the value of r into the formula, we get 31.4 cm = 2 * 3.14 * 10 * C.

The diameter of the circle is 62.8 cm.
