C Value Calculator

How to Use the C Value Calculator

1. Enter the radius of the circle in the input field labeled "Radius (r)". Ensure you enter a positive number.
2. Click the "Calculate" button to compute the circumference.
3. The result, which is the circumference of the circle, will be displayed in the "Circumference (C)" field.
4. If you need to start over, click the "Reset" button to clear all input fields.

Working Principle

The circumference of a circle is the distance around its edge. It can be calculated using the formula C = 2πr, where:

• C is the circumference.
• π (pi) is a mathematical constant approximately equal to 3.14159.
• r is the radius of the circle.

Example

If the radius of a circle is 5 units, the circumference can be calculated as follows:

C = 2 * π * 5 ≈ 2 * 3.14159 * 5 ≈ 31.4159 units
