    Yep, pi day for me is when I indulge in some Cherry pie🍒By the way, I was about 4years old when I first saw the pi symbol. When Mom put a slice of pie in Dad's lunch pale. It was in a plastic, wedge shaped container that had the math symbol for pi.😋

    Small correction, pi~22/7 ~ 3.142857 followed by 142857 recurring. This stems from any number divided by 7. The rational approximation presented in the video stems from another closer approximation to pi, namely pi~355/113~3.14159292035...... To help in remembering this ratio ,note the pattern in 113355= 113 355 , bearing in mind the ratio to pi should be about 3 . This is possible when taking pi~ 355 divided by 113.

    Thank you 👍 for this ,can you explain the use of pi in Other mathamatic formulas please? Because i want to know it very deeply.

      Sure I will upload a video about it soon.

    I wonder how every next digit of pi is known even though it’s irrational and therefore doesn’t repeat a pattern. When it comes to roots of imperfect products, they’re irrational but the next digit is always consistent as it’s the highest number that doesn’t exceed the target number when raised to the same power as the root.

    why the c & d are cannot be the rational ones at same time ?

    At 2:56,
    he says 22/7 = 3.14159.
    that's incorrect. 22/7 = 3.142857

    Why at least one (C or D or both) must be irrational?

      That is a fundamental property of a circle.

    This video omits, ignores or hides an essential aspect of pi. Pi is NOT always an irrational constant. Sure it is 3.1416 or whatever during the day. But, at night it varies usually between 2.7 and 4.3. Occasionally it is even higher; two weeks ago I got up to tinkle and noticed pi was a bit over 6. Apparently, for some unknown reason, pi is correlated with the tides in Perth, Australia.
    -- just thought you shoild know.
    The tragic recent collapse of the Titan sub is probably due to this variation unless they wound the hull only during day time ant stopped at sundown.

      @@Dominic51214 The next place after the 5 is 9, so we round up. Of course that is pi at local noon and 68 degrees F at sea level. As i noted above, all bets are off at night and at New Year’s day.

      @@robadoba8497 whoa! I did NOT say pi changes with time. I said it varies. Although we at first thought the night-time fluctuates were random, as noted above, we have recently detected a correlation between pi and tides in Perth, Australia. We think this has something to do with morning kangaroo hopping or perhaps numbat (noombat to some) activity. Clearly, more study is needed. In meantime, do not use pi in calculations after 10 PM EST.

    Nobody knows what Pi is. Actually you can never calculate the area of a circle, because you don't know Pi.
