This tool calculates the area of a circle based on the radius you provide.
How to Use the Circle Area Calculator
This calculator helps you to easily find the area and circumference of a circle based on the radius you provide.
- Enter the radius of the circle in the input field labeled “Radius (r)”.
- Enter the units of measurement (e.g., cm, m, in, etc.) in the input field labeled “Units”.
- Click on the “Calculate” button to see the results.
How It Calculates the Results
The calculator uses the following mathematical formulas:
- Area of the Circle ((A)) = π × radius²
- Circumference of the Circle ((C)) = 2 × π × radius
Where π (pi) is approximately equal to 3.14159.
Limitations
The calculator assumes ideal conditions and provides results based on the input values. Ensure you input a positive number for the radius. The units should be a non-empty string.
