Ellipse Area Calculatrice

An ellipse is an oval shape defined by two radii: semi-major axis (a) and semi-minor axis (b). Area calculation is simpler than circumference, using a straightforward formula.

Enter semi-major axis a Then: Enter semi-minor axis b Then: Multiply π × a × b.

Example: Input a = 8 cm, b = 5 cm gives a result of Area ≈ 126 cm² (π × 8 × 5 ≈ 126).
