A hexagon is itself a polygon so it makes little sense to ask about hexagons and polygons. In any case, there were no polygons in the official soccer ball at the 2014 FIFA World Cup in Brazil. The ball was the Adidas Brazuca and it was made from six rounded cross-like shapes.
The official size of a soccer ball is not more than 70 centimeters (27 inches) in circumference and not less than 68 centimeters (26 inches) in circumference. And in case a question arises regarding the metric units not being the exact equivalent of the standard or English units (or vice versa), refer the inquiring individual to the Federation Internationale de Football Association (FIFA), the world governing body of soccer and the ultimate authority on the game and its rules. The dimensions are right out of the official Laws of the Game that they publish.
