A football, however, owes its two-dimensional origin to the ellipse rather than the circle, giving the pigskin its prolate spheroid shape, which has a polar axis that is greater than its equatorial diameter.
Is a football a sphere shape?
Most modern Association footballs are stitched from 32 panels of waterproofed leather or plastic: 12 regular pentagons and 20 regular hexagons. The 32-panel configuration is the spherical polyhedron corresponding to the truncated icosahedron; it is spherical because the faces bulge from the pressure of the air inside.
Is a football an ellipse?
Football and rugby are played with balls that are based on ellipses. An ellipse has two axes, a long major axis and a short minor axis. When a solid is made by rotation around the major axis, it is called a prolate spheroid, the shape of a football.

A football is a prolate spheroid, and it's shaped that way because that's also the shape of an inflated pig's bladder, which is what the first footballs were made of. Soccer balls were also made of pig's bladders, but as soon as technology permitted, those balls got rounder, which made them easier to kick.
Is oval a shape?
An oval shape is a 2D shape, similar to an egg, that has no straight lines and vertices. The oval shape has one flat face, which does no self-intersect at any point. Another way to describe an oval shape is by saying that it is similar to a smooshed circle, a circle that is elongated in a way.
