Answer 1

A basketball is an inflated spherical ball used in the game of Basketball. Basketballs typically range in size from very small promotional items possibly only a few inches in diameter to extra large balls nearly a foot in diameter used in training exercises to increase the skill of players.[1] Nearly all basketballs have an inflatable inner rubber bladder, generally wrapped in layers of fiber and then covered with a tacky surface made either from leather (traditional), rubber, or a synthetic composite. As in most inflatable balls, there is a small opening to allow the pressure to be increased or decreased. The surface of the ball is nearly always divided by "ribs" that are recessed below the surface of the ball in a variety of configurations and are generally a contrasting color. A standard 29.5 basketball has about 4118 pebbles,with the pebbles being at a diameter of 2.5 millimeters. An orange surface with black ribs and a possible logo is the traditional color scheme of basketballs but they are sold in various colors. Balls are generally designated for indoor (generally made of leather or absorbent composites), or all-surface use (generally made of rubber or durable composites, also known as Indoor/Outdoor balls). The abrasiveness of asphalt and the dirt and moisture generally present in an outdoor setting will usually ruin an indoor ball within a very short period of time.

Answer 2

Basketball was originally played with a soccer ball. The first balls made specifically for basketball were brown, and it was only in the late 1950s that Tony Hinkle, searching for a ball that would be more visible to players and spectators alike, introduced the orange ball that is now in common use.

A round ball made of rubber, leather or synthetic leather. Comes in 3 different sizes (size 5, 6 or 7).

Answer 3

It all depends on who the ball is made for! An NBA basketball is made of composite leather, a synthetic material designed to withstand slam dunks and allow all-stars like Kobe Bryant to keep a good grip as they go for the ally-oop! WNBA balls are also made of composites but are slightly smaller because female players tend to have smaller hands. High school and college stars use real leather balls sometimes. Rubber balls are for novice players and are great for street games because of their durability. Beneath the surface, deep within each basketball lies a gridwork of nylon, rubber, and a material called butyl. These layers help the ball stand up to hours of double dribbles.

Answer 4

Leather

Answer 5

These days, it is made with Synthetic Rubber/Plastics. But originally it was made of hide (leather). Even the ball got greener (environment friendly and also animal friendly - usage of leather is deprecated these days) dont let Maneka Gandhi know if you plan to use real leather (who cares if humans die, they get their votes by yelling from the rooftop about animals)
