The diameter of the midpoint of the football field, and the diameter of the middle circle of the foo

The middle circle is meters.

The midpoint is a foot in diameter and is almost 33 centimeters.

Don't be too big for the football projection.

The football pitch in the middle of the standard 400-meter track is very standard.

The radius of the circle is meters, so the diameter is meters.

Middle circle radius: Draw a circle with a radius of meters (10 yards) from the center marker.

Other Football Field Sizes:

The playing field must be rectangular and the length of the sideline must be longer than the length of the goal line.

Length: Minimum 90 m (100 yd) Maximum 120 m (130 yd) Width: Min 45 m (50 yd) Max 90 m (100 yd) International competition standard.

Length: Minimum 100 m (110 yd) Maximum 110 m (120 yd) Width: Min 64 m (70 yd) Maximum 75 m (80 yd) Size of the field:

The playing field must be rectangular and the length of the sideline must be longer than the length of the goal line. The length is 90-120 m (100-130 yd) and the width is 45-90 m (50--60 yd).

International competitions: length 100-110 m (110--120 yd), width 64-75 m (70-80 yd).

World Cup final stage: length 105 meters (about 115 yards), width 68 meters (about 74 yards).

A penalty spot is set 11 metres (12 yards) from the midpoint of equal distance between the goal posts in the penalty area. Outside the penalty area, draw an arc with a radius of 10 yards (10 yards) from each penalty spot, called the top of the arc.

100 meters, you can measure it.

Hello, hello, I am your Qingqing teacher, I am happy to serve you, I have received your question, I will reply in time after reading, after asking, because there are too many lists, I will answer in turn, I will not answer, please be patient! 

Summary; Generally, grass seedlings are between 30 and 60 mm, the number of needles in rows is between 130 200 mm, and the row spacing is between 5 and 12 mm. It can be used in football fields, tennis courts, hockey rinks, golf courses, gymnastics, track and field, etc., and is a multi-functional and fitness venue material. It does not need to be manually seeded, fertilized, pesticide, watered, pruned and other management work, and can be used around the clock, regardless of the restrictions of the competition venue.

I hope my answer can make you satisfied Finally, please help me in the lower left corner of the "I want to evaluate" there to give a like, thank you, I wish you a happy life, all your wishes come true, good luck, all the best! 

1) Venue area: The playing field shall be rectangular, and its length shall not be more than 120 meters or less than 90 meters, and the width shall not be more than 90 meters or less than 45 meters (the length of the venue for international competitions shall not be more than 110 meters or less than 100 meters, and the width shall not be more than 75 meters or less than 64 meters). In any case, the length must exceed the width.

2) Draw lines: The playing field should draw clear lines according to the floor plan. The line width shall not exceed 12 cm, and shall not be made into a U+201CV U+201D shaped groove.

The longer two lines are called the sidelines, and the shorter two lines are called the goal lines. Draw a line across the court in the middle of the field, called the center line. The site should be marked obviously, and with this point as the center of the circle, with meters as the radius, draw a circle called the middle circle.

A flat-topped flagpole not less than a meter high should be erected at each corner of the site, and a small flag should be tied to it; Similar flags and flagpoles may be erected on one side each, at least 1 metre outside the sideline of the centerline on either side of the field. (3) Goal area: On the goal line at both ends of the playing field from the inside of the goal post, draw a long line perpendicular to the goal line to the field, one end is connected with the goal line, and the other end is drawn a connecting line parallel to the goal line, and the area within the range of these three lines and the goal line is called the goal area.

4) Penalty area: On the goal line at both ends of the playing field from the inside of the goal post, draw a long line perpendicular to the goal line to the field, connect with the goal line at the upper end, draw a connecting line parallel to the goal line at the other end, and the area within the range of the goal line is called the penalty area. Make a clear mark at the midpoint of the two goal lines perpendicular to the field 11 meters each, called the penalty spot.

Take the penalty spot as the center of the circle and the meter as the radius, and draw an arc outside the penalty area, which is called the free throw arc. (5) Corner kick area: take the intersection of the sideline and the goal line as the round point, with a radius of 1 meter, draw a quarter of the arc to the field, and the area in this arc is called the corner kick area.

6) Goal: The goal should be located at the ** of each goal line, consisting of two meters apart, equal distance from the two corner flags, upright goalposts and a horizontal crossbar with a lower edge of the ground meters from the ground, in order to ensure safety, whether it is a fixed goal or a movable goal must be stably fixed on the field. The width and thickness of the doorposts and crossbars shall be symmetrically equal and shall not exceed 12 cm.

The net is attached to the goalpost behind the goal, as well as to the crossbar and to the ground. The net should be propped up properly so that the goalkeeper has plenty of room to move! The standard diameter of a soccer ball is the standard for the circumference of a sphere as defined by FIFA.
