The game of soccer is one of the most popular sport in the modern era and it is played using soccer balls.The standard soccer ball size is size 5 with a circumference of 69cm (27 inches).
The history of these balls dates back to 1855 when Charles Goodyear manufactured and designed spherical balls and in 1863, the English football association was formed. In the year 1873, it was decided that the soccer ball must be spherical with a circumference of 69 cm-71 cm(27 inches-28 inches) while in the year 1937 a weight of 400 grams-450 grams was established and that soccer balls must be covered by leather or any of the approved material.
Most modern balls are stitched from 20 regular hexagon and 12 regular pentagons to form a 32 panel of waterproofed leather or plastic. The 32 panel configuration is the spherical polyhedron corresponding to the truncated icosahedron and it is spherical because the faces bulge from the pressure of the air inside.
The first set of the above described balls was sold in the 50s in Denmark and it became common in Europe in the 60s meanwhile the said configuration was publicized by Adidas tel star which was the official ball used in 1970 World cup.Soccer balls are made by stitching non water proof plastic similar to the designed seen in volley balls and are laced for good access to the internal air bladder.
