Final answer:
The calculator for ellipses provides information about the shape, roundness, and area of the ellipses.
Step-by-step explanation:
The calculator for ellipses provides information about various aspects of ellipses, including their shape and area. Specifically, the calculator can help determine the eccentricity of an ellipse, which is a measure of its elongation or roundness. Additionally, the calculator can calculate the area of an ellipse using the formula A = лab, where 'a' is half the length of the major axis and 'b' is half the length of the minor axis.
