Advanced geometry calculators handle three-dimensional solids and curved surfaces — ellipses, tori, ellipsoids, frustums, and regular polygons — requiring more sophisticated formulas than basic shapes.
Stapsgewijze handleiding
- 1Ellipse area: A = πab (semi-axes a and b)
- 2Torus volume: V = 2π²Rr² (major radius R, tube radius r)
- 3Regular polygon area: A = (n × s²) / (4 × tan(π/n))

Invoer
Ellipse with semi-axes a = 8, b = 5
Resultaat
Area = π × 8 × 5 ≈ 125.66 sq units
When a = b = r, the ellipse becomes a circle
