Calculate geometric properties including area, perimeter, circumference, surface area, and volume for 2D and 3D shapes.
Computed for circle
| Parameter | Calculated Value |
|---|---|
| Radius (r) | 10 |
| Diameter (2r) | 20 |
| Area (π * r²) | 314.16 sq units |
| Circumference (2π * r) | 62.83 units |
Standard geometric formulas for Euclidean 2D planar and 3D spatial solids.
A circle with a radius of 10 units.
Area = π * 10² = 314.159, Circumference = 2 * π * 10 = 62.83.
Area is 314.16 sq units, Circumference is 62.83 units.
Tested against 2+ automated test cases via Vitest. Formulas are continuously checked against edge cases to prevent calculation drift.
Cross-verified against Microsoft Excel / OpenXML formula engines (PMT, SUM, IPMT) and statutory financial standards.
