The volume of a sphere is (4/3)(Pi)r3. A Basketball is 9.34 inches in diameter, while a BB has a diameter of 0.172 inches, so dividing the volume of a basketball by the volume of a BB, we get [(4/3)(pi) * 4.67^3] / [(4/3) pi * 0.086^3] = 4.673/0.0863 The calculation is left as an excersise to the student. * The above is based upon the assumption that the BBs will occupy the volume of the basketball with 100 percent efficiency. The trouble is, they won't, so the correct answer will be somewhat less than the above calculation predicts. Spheres typically pack with 60-75% efficiency. Since BBs are very small compared to the basketball, the efficiency should be closer to the high side of that range. If you filled the basketball with ping-pong balls instead of BBS, the efficiency would be lower. See more at http://mathworld.wolfram.com/SpherePacking.html or http://www.ics.uci.edu/~eppstein/junkyard/spherepack.html. * This sounds like it could become a really interesting problem, because you would have to deal not only with the BB-to-BB packing issues, but also how efficiently they stack against the curved wall. A non-regular packing might turn out to be more efficient than a regular one. And what of the manufacturing tolerances on the BBs? If you were looking for a master's thesis topic, you might have found one.
There are several methods for filling a basketball with water. One method involves carefully removing the plug from the inflation hole in the ball. Filling the ball, replacing the plug, and taping the entire ball to prevent leakage.
Basketball was first played with a round ball and two peach baskets nailed to a 10 feet high elevated track. The game was developed in 1891 by Dr. James Naismith.
You have to squeeze the ball with your hands. if its hard to do that. Bounce the ball on the ground. If it bounces up to like 3 or 4 feet up in the air when you just drop it. Then you have enough air.
Soccer balls do not contain helium. if they did, they would float like a balloon! Actually, that's not true. A soccer ball would NOT float like a balloon--they weigh too much. It would, however, increase the distance ever so slightly over that of a regular air filled soccer ball. Eventually over time, the helium would dissipate, much like a helium balloon that slowly falls to the ground.
Which is not a form of insulation loose fill foamed-in-place ball batt
It Floats, try it. It's hilarious.
Blow inside the ball through the hole!
i need someone to help me
a lot soccer balls hold quite a bit of air if you can contain at least 50 farts, you will have more then enough to fill a soccer ball only fill until its 15 oz in weight
Because the ball is shot into a net.-Also, because the first hoop was a peach basket- hence 'basket'ball.A Canadian doctor, Dr. Naismith , first had the idea to create a game that would fill gymnasiums during wintertime. After long and deep thoughts, he found this principle: two teams must throw a ball into a basket. At the very beginning , the basket was not pierced but they rapidly decided to do so. (To make the game quicker)
Regular air is perfectly acceptable. To fill it, get a bike pump with a small needle that will fit the small black hole on your basketball and pump air through the tube on the system, through the needle and into the basketball until it is inflated as much as you like. You can buy a bike pump/air pump at almost anywhere including walmart or walgreens.
