Use this tool to quickly find the circumference of a circle from its radius.
How to Use the Circumference Calculator
To use this tool, follow these steps:
- Enter the radius of the circle in the input field. The radius must be a non-negative number.
- Specify the precision or the number of decimal places you want in the result.
- Click the “Calculate” button to view the circumference.
Explanation of How the Calculator Works
The circumference of a circle is calculated using the formula:
Circumference = 2 × π × radius
Where π (pi) is approximately equal to 3.14159. The radius is the distance from the center of the circle to any point on its perimeter. The result can be displayed to the desired number of decimal places based on the precision you specify.
Limitations
This calculator has some limitations:
- The radius must be a non-negative number.
- The precision must be a non-negative integer.
- Large values for the radius or high precision can lead to rounding errors due to limitations in floating-point arithmetic in JavaScript.
