Ellipse Area

Area is a numerical characteristic of a two-dimensional (flat or curved) geometric figure, informally speaking, showing the size of this figure. Historically, the calculation of the area was called quadrature. A figure having an area is called quadratic.

Ellipse — is a closed curve on a plane that can be obtained as the intersection of a plane and a circular cylinder or as an orthogonal projection of a circle onto a plane.

The area of the ellipse is equal to the product of the lengths of the major and minor axes of the ellipse by the number pi (3.1415). Ellipse area formula is pirR.
