The pitcher throws the ball, the ball is hit, he runs, first base, second, third, home run! The bat and ball game that stirs the many crowds at the stadium, baseball, was in history from as early as the 18th century, before the Civil War even started. As a matter of fact, baseball became so popular in the United States, it has become known as the "National Pastime." The objective of this pastime is to score more home runs than the opponent.
The most common fact people know about baseball is that it has a field consisting of four bases forming a diamond, but not many knows the area of a field or even want to know It is simply vague to talk about the area of a baseball field, because there are different areas for different leagues. All infields of a Baseball field must be identical, which means from base to base, it's 90ft apart. The outfield, however does not have set values.This is why no two baseball fields have exactly the same dimensions. The area of a baseball field can also vary with difference in base lengths. For example a field with bases with less distance apart would have a smaller area.
There are four leagues that include Baseball, Little league, Pony League (Protect Our Nation's Youth), and Babe Ruth League. For Little, Babe Ruth and Pony League, there is a required area (as shown in chart 1 and the results above). From these measurements, most can probably notice that the area of the field of the Babe Ruth league and Baseball are much greater than that of the Pony League and Little League. The four leagues are organizations set up for the youth. The difference between the Pony League and the Little League is that the players of the Little League start pitching at seven or eight, while players start to pitch at nine in the Pony League.
Since baseball fields in general are in the shape of one fourth of a circle, we can divide the area of a full circle by four. Therefore, if we know the radius from the home to the outfield wall, we can plug the radius into the formula…
A = ½πr²
and get the area of a baseball field.
So, next time you go to a baseball game, bring your "peanut butter and crackerjacks" and be sure to check the field out.
