Elips Hesaplayıcı

Bir elipsin alanını, dışmerkezliğini ve odaklarını hesaplayın.

Giriş

Ellipse Calculator — Compute area, eccentricity, and foci of an ellipse. Enter Semi-major axis, Semi-minor axis to get an instant, accurate result.

Formül

Area = π×a×b. Eccentricity = c/a where c = √(a²−b²). Perimeter is estimated with the Ramanujan approximation: π×(3(a+b) − √((3a+b)(a+3b))), where a and b are the semi-major and semi-minor axes.

Adım adım

  1. Enter the Semi-major axis.
  2. Enter the Semi-minor axis.
  3. Click Calculate to see your result instantly.

Gerçek dünya örneği

Example: With Semi-major axis = 5, Semi-minor axis = 3, the Ellipse Calculator gives Area: 47.1239, Eccentricity: 0.8, Foci Distance: 4.

Sıkça Sorulan Sorular

Why is the perimeter only approximate?
There is no exact elementary formula for an ellipse's perimeter; the Ramanujan formula used here is a highly accurate approximation.
What does eccentricity tell you?
It measures how elongated the ellipse is — 0 is a perfect circle, and values closer to 1 are more stretched.
What inputs does the Ellipse Calculator need?
You'll need to provide: Semi-major axis, Semi-minor axis. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Ellipse Calculator?
The Ellipse Calculator applies the formula exactly as calculated — Area = π×a×b. Eccentricity = c/a where c = √(a²−b²). Perimeter is estimated with the Ramanujan approximation: π×(3(a+b) − √((3a+b)(a+3b))), where a and b are the semi-major and semi-minor axes. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Ellipse Calculator free to use?
Yes, the Ellipse Calculator is completely free, requires no signup, and runs instantly in your browser.

Elips Hesaplayıcı Hakkında

The Ellipse Calculator uses a real, verifiable formula — Area = π×a×b. Eccentricity = c/a where c = √(a²−b²). Perimeter is estimated with the Ramanujan approximation: π×(3(a+b) − √((3a+b)(a+3b))), where a and b are the semi-major and semi-minor axes. — so results are accurate every time, not an approximation.
