The final "2" isn't accurate; as the following digit is 6, the 2 would round up to 3. This can be corrected by changing the mnemonic to: "How I wish I could calculate PIE." My favorite pi recipe: "Start with eight squared plus seven, divide by eight squared plus seven squared, then multiply by five."

@@christopherstoney4154 When it comes to π nothing is really accurate. While it is correct that you would have to round up due to the following digit being 6, this is only the case if you want to terminate the digits here (which makes it a rational number that isn't technically _equal_ to π). The sixth digit after the decimal point is in fact 2. You could also fix this by writing π = 3.141592...

This is the most logical explanation of pi

I always learned: "Circumference = π • diameter" I always thought everyone understood pi as being the ratio between the circumference and diameter of a circle, but this video brought back a memory. When I first saw someone write C=2πr, I was so confused why they used a more complicated and abstract formula. C=πd is so much simpler and tells you explicitly what you showed in this video. It makes sense if you learned C=2πr, you wouldn't get the same intuitive understanding of what pi is. By the way, I would recommend you measure the diameter instead of the radius, because measuring the diameter gets you a smaller relative error of the measurement.

maybe as it is helpful with the area of a circle being π r2

The 3.14 constant comes from: whenever you divide the circumference of any circle to its diagonal from the center; no matter how big or small the circle is you always get 3.14

This is put together very well! You always sound so happy while talking about all this which makes it feel very welcoming

Good question!

This is a really nice explanation of what Pi is / where it comes from. It is NOT a demonstration of how Archimedes determined a more precise value than "a little more than 3". Pi is only approximately 3.14, and Archimedes didn't have access to numbers written in decimal form anyway - they hadn't been invented yet. He was able to work out (using a very brilliant geometric method) that the number of diameters it takes to equal the circumference has to be between 3 10/70 and 3 10/71. That was enough precision for him, and it gives us 3 1/7 (22/7) which is about 3.148. Would love to see you make a video showing that method!

Use that as your decimal. You wrote down 3.14 out of nowhere because that was what we were told pi was in school. The straight line distance divided by the diameter of your wheel is the way to go, if you don't know about 3.14 ahead of time.

22/7 (3.1428) was Archimedes upper boundary for PI not PI itself. Archimedes said PI lies between 3.1408 and 3.1428 which is approximately 3.141. Of course he stated it in fractions not decimals. 223/71 < π < 22/7 or 3.1408 < π < 3.1428 So pi must be ~ 3.141_

Math teachers think in numbers and don’t understand that others think in images. They don’t get it so carry on the old way

I figured this out in 4th grade by experimenting with various coins as my “wheel”. We hadn’t learned fractions yet so all I could say was “the distance around a circle is a little bit more than three times the diameter.” Well actually I didn’t know the word diameter yet so it was “A little bit more than three times across the circle.”

I always thought he used geometry and trig to get a precise number....he used a 6-sided hexagon inside a circle worked out the circumference of that, then made it into a 12-sided shape and got the circumference, made _that_ into a 24-sided etc etc until he'd made a 96 sided shape and was able to figure out pi to about 10 digits. Good effort though, certainly at the conceptual level of probably most people.

After that they try again with diameter is 7 and this time the circumference is 22 and it's a whole number. So, I call it a pi. Yes I made this up.
