I don't quite understand what you're talking about.

Determine the starting line.
The formula is: wn=2 [r+(n-1)+. The method of calculating the forward extension of the starting line is the length of the curve of a certain lane minus the length of the curve of the first lane, which is the number of starting line extensions of the lane.
If both runners run their own lane for 1 week, the runner in lane 2 will run more than the runner in lane 1. In order for the 2nd lane to be equal to the distance traveled by the runner running the 1st lane, the starting point must be extended some distance forward. The distance that should be stretched forward is called the number of starting line extensions.

The difference in length between two adjacent runways is the difference of 2 ring widths
-
C small one minus c small two d small one minus d small two (d small one minus d small two).
-
(The distance between the two straights + pi.)
-
2 times the pi multiplied by the runway width.
-
Two straights + 2 wide pi.

1. The standard runway is 400 meters long, the innermost radius of the curve is 36 meters, and the width of each runway is meters, with a total of eight curves.
1.What is the radius of the fourth curve?
2.What is the radius of the 7th curve?
3.If the 200m leg is a 200m run, how many metres is the fourth lane ahead of the athletes' starting point in the second lane?
4.If you run the 400-meter race, how many meters is the third lane ahead of the athlete's starting point in the second lane?
5.In the case of a 400-meter run, how many metres is the 8th lane ahead of the athletes' start in the 4th lane?
6.In the case of an 800-meter run, how many metres is lane 5 ahead of the start of lane 3?
2. Shengli Primary School runs to a total length of 200 meters, the innermost radius of the curve is 20 meters, each track is one meter wide, and there are six curves.
1.What is the second corner radius?
2.What is the radius of the fifth corner?
3.How many meters is the straight?
4.In the case of a 200-meter run, the third lane is about how many meters ahead of the athlete's starting point in the first lane.
5.In the case of a 400-meter run, how many metres is the starting point of lane 6 compared to the start of lane 4?
Another way to determine the starting line, good plus points.

I'm also waiting for the answer to this question, have you figured it out?
-
The 400-meter standard runway has a radius of 36 meters and a runway width of one meter.
The circumference of the first lap of the track is 2*m.
The circumference of the runway on the second lap of the runway is 2*.
meters wide of the runway, the circumference of the runway in the second lap.
The circumference of the track on the second lap minus the circumference of the track on the first lap.
Meters = meters. Meters = meters.
The width of the runway is meters, and the runway around the adjacent runway needs to be advanced by meters.
The width of the runway is meters, and the runway around the adjacent runway needs to be advanced by meters.
-
2*mmi.
Meters = meters. Meters = meters.
-
Diameter, circumference, runway full-field, add each time.

The length of the first two curves (calculated line length) is:
2 A curve is long.
Two straight lengths = full length of the runway - two curves length.
400m a straight section is long.
The total length of the runway = two curves + two straight sections.
The calculation of the length of each lane in 400m cn=2 [r+(n-1)d+number of starting line extensions. The formula is as follows:
wn=2π[r+(n-1)+
What is your education, major? It's good to have ambitions, but you have to be realistic, if you feel that you have a certain specialty, or are very interested in a certain major, and then have a goal to cultivate, don't blindly aspire.
The distance between the start and end of the 400 is 400 meters, and the cow handle, you don't need to count it.
Of course not. If you don't apply for cram school, the child has good study habits, a good foundation, and parents have the conditions to tutor their children, and they can also let their children achieve a relatively ideal grade. After signing up for cram school, in addition to sleeping, he chats with others in the cram school, and he doesn't listen at all, so it is useless for you to report to him no matter how many classes you give him. >>>More
Life goals are set by themselves, Bi Shumin said, life has no meaning, but we have to give it a certain meaning. Only when there is a lofty goal in life can there be the motivation to keep moving forward, insist on persevering and persevering, even if you don't reach it in the end, you can get closer and closer! >>>More
The first thing to do is to determine if the wifi module is really damaged, because under normal circumstances, the chances of these hardware being damaged are very small. So there are many times when it's not the hardware that's broken, it's a temporary shutdown of service. If you can't be sure, you can restart the phone, or restart the wifi function, if you restore it, it means that it is not broken, if you still can't use it, you can only go to the repair point for repair. >>>More
