Here I show how to find the perimeter of the circumscribed hexagon and then the circumscribed 12-gon to get two approximations for Pi

  • This helped me understand how to do your problems, thank you. You videos really do help!

  • fucking hell the sound is killing me.

    cant listen to that torture any longer than 1 minute.

  • pie was invented in India..along with chess numbers 0to 9..and the decimal system etc

  • actually we cant find really the real end of pi because we only presume some approximations regarding some of the measurements we take and in reality our approximation is not that perfect measurement of the define ratio of the diameter and its circumference as a result it appear to be infinite and also take note even standards that we are using today which are kept at sevres france aren't that perfect measrement or defne unt it has stil erors. so we cant mke it to end but one thing is sure 8 nds

  • excellent demonstration though. thank you

  • in your calculation for x using pythagorean theorem you have x^2 +(2x)^2 = .5^2 but it should be (2x)^2 - x^2 = .5^2.

    just a sign error

  • I think it should be Root 3 / 2. not 1 over 2 root 3
