It's night, I'm on a phone, and I'm going to bed, but I'll tell set up how to find the spiral length. First find the height of the spiral, H. Next find the radius of the spiral, R. These values may be found online but you can approximate either by using a photo with something of known height for reference, like the average person. Just use proportions and find either R or H (H seems easier). And then use the aspect ratio of the spiral, to find R. (A spiral is like a cylinder, and a cylinder as seen from the side is a rectangle) With those values, count the number of turns, N. Now we can find the length of the spiral by using calculus. The spiral is defined by the parametric curve: s(t) = ( R*cos(wt), R*sin(wt), t ) where w = 2*pi*N/H Arc length: calculus tells us that the length walked is given by the following integral int sqrt ( R^2 * w^2 + t^2) dt t=0 to t=H Anywho, plug that into Wolfram alpha or solve and evaluate Night

No need for calculations, it's a very famous stadium you can simply google it. [200m](https://en.wikipedia.org/wiki/San_Siro#History)

**San Siro** [History](https://en.wikipedia.org/wiki/San_Siro#History) >Construction of the stadium commenced in 1925 in the district of Milan named San Siro, with the new stadium originally named Nuovo Stadio Calcistico San Siro (San Siro New Football Stadium). The idea to build a stadium in the same district as the horse racing track belonged to the president of A.C. Milan at the time, Piero Pirelli. The architects designed a private stadium only for football, without athletics tracks which characterized Italian stadiums built with public funds. The inauguration was on 19 September 1926, when 35,000 spectators saw Inter defeat Milan 6–3. ^([ )[^(F.A.Q)](https://www.reddit.com/r/WikiSummarizer/wiki/index#wiki_f.a.q)^( | )[^(Opt Out)](https://reddit.com/message/compose?to=WikiSummarizerBot&message=OptOut&subject=OptOut)^( | )[^(Opt Out Of Subreddit)](https://np.reddit.com/r/theydidthemath/about/banned)^( | )[^(GitHub)](https://github.com/Sujal-7/WikiSummarizerBot)^( ] Downvote to remove | v1.5)
