there are about 720 dots going around the Basketball. We Will say there are 720 "dot units". This is the circumference. To find the diameter of the basketball in dot units, divide 720 by pie(3.14). Divide this by 2 for the radius (Circ = 2*pie*r). Now we must find the area for the basketball expressed in dot units. Area of a circle is pie*r^2. This gives us 41,274. This is just an estimate and is probably off by at least a couple thousand. ---- there are about 760 kristins on a basketball According to the Spalding website, (http://www.spalding.com/contact/contact.html#Q6), there are 122 pebbles per square inch on a Spalding basketball which makes approximately 35,000 pebbles total.

Usually between 300-500.

There is no set number, manufacturers claim that they have the optimum number and arrangement of the dots.

Titleist ProV1 (a market leader) has 394

It depends on the manufacturer, style of the ball, size (if it's standard size or not)...

### How many dittos are on the surface of a basketball?

I can't tell you exactly, but I can tell you how to estimate the number of dots on a basketball. First, measure a 1 inch square on the surface of the basketball and count the dots it contains. Then use the formula for the area of a sphere, which is: 4PR2, or 4 times Pi times the radius squared. An official men's pro basketball is 9 inches in diameter, so the radius would be 4.5 inches and the formula would work out like this: 4 times 3.14 times 20.25 equals 254.34 square inches. Measure any areas on the basketball that have no dots and subtract that area from the total square inches arrived at above. Now multiply this number by the number of dots you counted and you've got a decent approximation.

### What is screen-resolution?

Refers to the sharpness and clarity of an image. The term is most often used to describe monitors, printers, and bit-mapped graphic images. In the case of dot-matrix and laser printers, the resolution indicates the number of dots per inch. For example, a 300-dpi (dots per inch) printer is one that is capable of printing 300 distinct dots in a line 1 inch long. This means it can print 90,000 dots per square inch. For graphics monitors, the screen resolution signifies the number of dots (pixels) on the entire screen. For example, a 640-by-480 pixel screen is capable of displaying 640 distinct dots on each of 480 lines, or about 300,000 pixels. This translates into different dpi measurements depending on the size of the screen. For example, a 15-inch VGA monitor (640x480) displays about 50 dots per inch.

### What does dpi stand for?
