**Steve**, Friday, December 9, 2011 at 11:35amWithout knowing the radius of the semicircular ends, this can't be solved. However, given that the radius is r on the inside lane, the circular part of the lane has circumference 2πr. The straight part is the same length for each lane.

So, the radii for the lanes are

r, r+1, r+2 ... r+7

Thus each lane is 2π meters longer than the one inside it.
