Frequently Asked Questions
Common questions about Ellipse Perimeter (Ramanujan) from Semi-Axes, formulas, and expected usage.
What does the Ellipse Perimeter (Ramanujan) from Semi-Axes calculator do?
It helps with estimating ellipse perimeter for layout, design, and engineering approximations.
What formula does the Ellipse Perimeter (Ramanujan) from Semi-Axes calculator use?
Ramanujan approximation: P ≈ π(a+b)[1 + 3h/(10 + √(4-3h))], where h=((a-b)²/(a+b)²).
What inputs are valid?
Semi-axes must be non-negative, the semi-minor axis cannot exceed the semi-major axis, and not both can be zero.
When would I use this?
estimating ellipse perimeter for layout, design, and engineering approximations
