Answer:
The correct answer is A and C.
Answer:
B
Step-by-step explanation:
You cant find the square root of ten. It is a decimal that keeps on repeating. Therefore, it is irrational.
Assuming that there are N lanes and runners are running in the middle of each lane,
width of each lane = (1/N) [m]turning of first lane = π×(R+(1/N)×(1/2))
turning of second lane = π×(R+((1/N)×(1/2))+(1/N))
you can get the difference in turning lane simply by subtracting turning of first lane from turning of second lane.
If i worked the problem correctly, it should be π×(1/N) meter difference between each lane
