Formula and methodology
Formula: Area = π × radius²; diameter = 2 × radius; circumference = 2 × π × radius.
This geometry page keeps the radius as the single required measurement and shows the most useful companion dimensions, with no hidden unit conversion.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Radius — units; minimum 1.0E-6; maximum 1000000000000
Worked example
| Input | Value |
|---|---|
| Radius | 5 |
Area = 78.53981634 square units, diameter = 10 units, and circumference = 31.41592654 units.
Assumptions and limits
- The shape is a flat circle and the radius is positive.
- All outputs use the same unit basis as the entered radius.
- π is evaluated using the JavaScript mathematical constant at full precision.
- The result does not account for thickness, surface roughness, or a non-circular shape.
