I'm both a nationally certified Tennis Instructor as well as a Mechanical Engineer, so I'm well-qualified to answer your question.\n\nAccording to the International Rules of Tennis, a tennis ball's diamater must lie between 2 1/2 inches and 2 5/8 inches.\n\nSince the mathematical formula for Circumference is 3.14 (Pi) times Diameter, a tennis ball's circumference must lie between 7.85 inches and 8.25 inches.

A standard single tennis court is 60 feet wide by 120 feet long. (60 x 120) The length and width of the court can be slightly larger or smaller depending on the application. The International Tennis Federation recommend a minimum court size of 56" x 114".

Bigger than a golf ball, smaller than a baseball.

Circumference = pi x diameter.\n\ndiameter = Circumference / pi\n\ndiameter = 40 / pi\ndiameter = 12.7323954 cm

Playing Lines: \nThe outside dimensions of the playing lines should be as follows: \nDoubles 36' x 78' (10.97m x 23.77m) \nSingles 27' x 78' (8.23m x 23.77m) \nAll lines should be not less than 1" (2.54 cm) nor more than 2" (5 cm) in width, except the base line which  may be up to 4" (10 cm) in width and the center line which should be 2" (5 cm) in width. \nClearance Between Courts \nWhere courts are constructed within the confines of a common enclosure, the distance between side lines should be not less than 12' (3.658m). Where space permits, it is desirable to provide additional space between side lines to enhance play; 24' (7.315m) is recommended. \nTennis Court Orientation: \nA tennis court should be laid out to minimize players looking into the sun when serving or when following  the flight of a ball. A tennis court also should be laid out to avoid distracting shadow lines and patterns on the court surface. \n\n\nHope that's alright x

The two best pool balls available on the market are the "Aramith Super Pro" set and "Brunswick Centennial" set.  There are lower grades of Aramith and Brunswick balls, but these are the top of the line for each brand and are comparable in quality.  The standard size for pool balls is actually 2 1/4" diameter.  Check out the websites for each brand for a more detailed description.  M.D.-BCA Instructor/Referee.

the answer to your question is simple..first find the equation for the circumference of a circle which would be 2 times pi times radius..which gives you the answer 29.516 if you round to the nearest 10th your answer would be 29.5cm

The circumference has to be approx. 9 inches according to MLB.com\n\nC=2*r*pi\ndivide both sides by 2\n4.5=r*pi\ndivide by pi\n1.45=r\nSo the radius of a baseball is approx 1.45 inches\n\nSoccer\nCircumferene must be about 28 inches\nC=2*r*pi\ndivide both sides by 2\n14=r*pi\ndivide by pi\n4.7=r\n\n\nSo, baseball radius approx = 1.45 inches\nsoccer ball radius  approx = 4.7 inches

According to official baseball rules, a baseball can have a circumference anywhere between 9 and 9.25 inches.  \n\nFrom the MLB website, rule 1.09:  \n\nThe ball shall be a sphere formed by yarn wound around a small core of cork, rubber or similar material, covered with two stripes of white horsehide or cowhide, tightly stitched together. It shall weigh not less than five nor more than 5 1/4 ounces avoirdupois and measure not less than nine nor more than 9 1/4 inches in circumference. \n\nA circumference of 9 inches corresponds to a radius of 1.432 in (= 3.638 cm) and a volume of 12.311 in^3 (= 201.733 cm^3).  (circumference = 2*pi*r, volume = 4/3 pi*r^3.)  A circumference of 9.25 inches corresponds to a radius of 1.472 in (=3.739 cm) and a volume of 13.365 in^3 (=219.016 cm^3).

hmm use a calculator...i am sure a ti-83 can show you how to do it, and/or this problem is impossible..but i am sure you can do it..or am i...man now you confused me you have this in the tennis section???

The three sizes that are used for play in adult slow pitch softball are 11", 12" and 16".  The 11" ball is a little bit harder and is used in women's play and by women on coed teams.  The 12" ball is used in men's play.  The 16" ball is used in areas where the fields are small (ball doesn't travel as far when hit), like big cities (Chicago for sure).  Hope this helps.

Circumference is 25,000 miles.  the diameter is about 7,950 miles, just under 8,000 miles (the earth isn't quite a sphere, it is a little pudgy at the equator, so the diameter varies slightly for our "oblique spheroid" which isn't a perfect sphere).

the circumference of a circle is the diameter * pi.\n\nor...\n\nC = d * 3.14

High school women's basketball typically uses the standard women's basketball, whose circumference is about 29 inches (730 cm) and weighs about 1 lb 3 oz (540 g).

Most tennis string packages come in 40 feet packages, some also come in 42 and 44 feet packages.  Most Standard tennis rackets with a 95 sq inch head can be strung with 35 feet of string.  This of course assumes that the frame has only 16 main strings and 18 cross strings.  For rackets with 18 main strings you need to add 2 feet of string.  Hope this helps.

specific diameter doesn't matter. keep it simple. get an over-sized head (to cut down on misses!) and make sure it is light (to avoid beginners wrist pain) a basic one from any regular sports store is fine. plus, you don't have to buy an expensive one. get like a $40-60 one and see if he likes tennis first!
