It depends on the make of the ball
Organic shapes don't have names. They are random shapes that you make up.
The triangle and rhombus pattern block shapes can be combined to make up a trapezoid.
round as the sun? round as a baseball/basketball/soccerball/other round object? square like a not so smart person?
There need not be any. The Brazuca, the official ball for the 2014 World Cup in Brazil was made from six rounded cross-shapes.
They are closed plane shapes which are bounded by five straight lines.
Well, the best soccerball in 2010 is, drumroll....... Jabulani!!!!
Two trapezoids can make up a hexagon.
