Ellipsoid Parameters

Semi-axis A

Semi-axis B

Semi-axis C

Semi-axis A is required.

Ellipsoid volume uses V = (4/3)πabc. If a = b = c, the shape becomes a sphere.

Live Results

Semi-axis A is required.

Formula

Volume: V = (4/3)πabc

Sphere equivalent radius: r = cbrt(3V / 4π)

Example: a = 3, b = 4, c = 5

Volume: (4/3)π x 3 x 4 x 5 = 80π ≈ 251.32741229

Sphere-equivalent radius: about 3.90885918
