Introduction: The Pi Day Calculator is a tool to calculate the circumference of a circle, making it perfect for celebrating Pi Day. Pi Day is an annual celebration of the mathematical constant π (pi), observed on March 14th (3/14). This calculator lets you explore the relationship between the radius and circumference of a circle.
Formula: The calculator uses the formula for the circumference of a circle: �=2��C=2πr, where �C is the circumference, �π is the mathematical constant pi (approximately 3.14159), and �r is the radius.
How to Use:
- Enter the radius of the circle in meters into the input field.
- Click the “Calculate” button to initiate the calculation.
- The result will be displayed, indicating the calculated circumference.
Example: For example, if you input a radius of 5 meters, the calculator will display “Result: 31.42 meters” on Pi Day.
