How to use Circumference Calculator?
Open the Circumference Calculator on your device, either online or as a mobile application.
Enter the radius or diameter of the circle into the appropriate field. Some calculators may have separate areas for radius and diameter, while others may calculate the diameter automatically based on the radius input.
Click or tap on the "Calculate" or "Find Circumference" button to perform the calculation.
The calculator will provide you with the circle's circumference in the appropriate unit of measurement, such as inches, centimetres, or meters.
If the calculator has additional features, you can also find the area of the circle or the diameter based on the radius or diameter input.
Repeat the process for any other circles you need to calculate the circumference.
The formula for calculating the circumference of a circle is:
C = 2πr
where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
Example:
Let's say you have a circle with a radius of 5 centimeters, and you want to find its circumference. Using the formula above, you would plug in the value of the radius:
C = 2πr
C = 2 x 3.14 x 5
C = 31.4 centimeters
Therefore, the circumference of the circle is 31.4 centimeters.
