As this question was originally placed in Australian football categories, it has been answered from that reference, as the same grounds are used for both - cricket and football - at different seasons of the year:
Firstly, there are no set dimensions for cricket or football grounds; most grounds can be anywhere from 137 to 180 metres in length and about 25 or 30 metres less in width. The minima laid down by cricket authorities are that length must be at least 137 metres and width at least 65 yards, but widths in real cricket pitches are never anything close to being so small.
So, if we take a ground of [say] 165 X 135 metres, you could virtually average those two figures and apply your mathematical formula for calculating the area of a circle => Area = pi X r X r, and, although not a 100% accurate method of calculating the area of an oval, the answer, via this method, would come mighty close, as the grounds are only mildly eliptical. And as grounds vary quite extensively, the answer would certainly be correct for many grounds in Australia:
The approx answer to the calculation is 70700 sq metres.
The reality is, however, that some grounds are larger, others smaller.
It is an oval field and has a 66ft.(20m.) strip of ground in the middle of the field.
Please Note: The same grounds are used for one day cricket and for T20 cricket - without size modification.
The dimensions are 7 by 12 meters Check: perimeter = 2*(7+12) = 38 meters and area = 7*12 = 84 square meters
The dimensions of a cricket field vary by location. There is no standard field size for cricket. It is a circle that has a diameter of 450 to 500 yards.
Aussie Rules football is played on cricket ovals so there are no standard dimensions for the field (usually called "ground" or "paddock"). The field should be an oval between 135 and 185 meters in length and 110 and 155 meters in width. (The Melbourne Cricket Ground is 160 meters long and 141 meters wide.) The boundaries are marked with a white line drawn a distance of a few meters from the stands.
The Ripken Stadium infield dimensions are 94 meters in the left field, 122 meters in the center field and 94 meters in the right field. Also, the max capacity of the stadium is 6,300 people.
AnswerLength of a standard cricket pitch is 22 yards(20.12 metres).This was based on the measurement Chain. which is 22 yards long.
8,536 square meters
No definite dimensions in Laws. Width can vary by about 40 metres and length likewise. Check Laws of the Game for precise figures.
Unit of length for the width of soccer field is meters.
The length is 10 meters and the width is 5 meters
Cricket Field :The cricket field consists of a large circular or oval-shaped grassy ground. There are no fixed dimensions for the field but its radius usually varies between 450 feet (137 m) to 500 feet (150 m).Cricket Pitch : cricket pitch is 22yds (66ft) from stump to stump and is 8'8" wide
105 x 68 meters for the Olympics.
It depends on how big the field is! It is 2.53 are.
