Calculate the eccentricity of an ellipse. The distance between the foci is 5.2 and the length of the major axis is 20.6.Round off your answer to the nearest thousandths (0.000).

The eccentricity of the ellipse is 0.252.

Explanation:

The eccentricity of an ellipse (), dimensionless, can be determined by means of the following expression:

(1)

Where:

- Distance between the foci, dimensionless.

- Length of the major axis, dimensionless.

If we know that and , then the eccentricity of the ellipse is:

The eccentricity of the ellipse is 0.252.
