(A) Cricket balls are generally made of three distinct materials: cork, string, and leather. The core of the ball is made of cork. That core is then wrapped tightly many times with string to reinforce it. The cork and string are then encased in leather, which is usually dyed either red (first class and Test matches) or white (one-day and Twenty 20 matches). Men’s cricket ball weight between 5.5 and 5.75 ounces (155.9 g to 163 g), circumference between 8.8125 and 9 inches (22.4cm to 22.9cm).
