Why is a ball spherical?
Balls can be spherical or not. The (American) football uses a ball that is far from spherical. However, a sphere is a perfect geometrical solid with a uniform radius, and a ball made in that shape is quite suitable for games. It will, for instance, bounce in a predictable way.
What is the mathematical name for the shape of a soccer ball?
The soccer ball is round in three dimensions. It's a sphere. (The Laws of the Game actually specify a spherical ball.)
Are all soccer balls spherical?
Soccer balls are not always spherical in shape; commonly, the surface of a soccer ball is composed of many hexagonal patches that are slightly ridged.
What shape can roll like an wheel excluding any type circle and cylinder?
A spherical shape like a ball.
What is the diameter of a football?
Football is the name given to a number of different team sports. All have fairly different measurements, and because many are elliptic (rather than spherical) they do not have diameters anyway. The only football with a diameter is the association football ball, which has a diameter of 21.6 to 22.3 centimetres.
