If you complete the circumference with all the string and there is no gap, Then why does it matter how many radiuses you fit around the circumference of a circle? If you enclose the circle then who cares what the ratio of radiuses to circumference is.
Essentially, it's because this ratio allows you to compute the area or perimeter of any circle. If you know radius or diameter, you can know the perimeter of the circle.
Thanks for an interesting question. This video shows that the circumference of a circle comes from the diameter going around the perimeter 3.14 times (or pi). They used an equation of pi = c/d: another way to say this is D x Pi = C or a full circle. Half a circle would only use have the diameter or one radius (2 radius make a diameter) Diameter=D Radius= R Circumference =C Pi= 3.14........ Full Circle. (D x Pi = C) or (R + R x P=Ci) or (2 x R x 3.14) Half a circle (D/2 x Pi) or (R x Pi) To learn more check out this video ua-cam.com/video/cC0fZ_lkFpQ/v-deo.html
I'm disappointed with my self , took me 26 years of living ,eating,shitting,sleeping to ask my self this question on 1:33 AM (what is PI why is it 3.14)
There may be a deeper solution to pi that involves "dimension". There may be a simpler explanation. I don't know. One thing that puzzles me is the meaning of pi. Is it really just a number? I dont think so. In language meaning either explains or describes. Pi is a very strange number. I think it's strangeness is due to missing meaning. Another way to look at pi is as an operator. An operator that, when applied to any line, gives a special kind of curve. A number that turns one shape into another. Is there an operator that turns lines into triangles? Squares? Toruses? Hyperbolas? If we could find those operators maybe they'd shed more light on what pi is.
@@kallianpublico7517. The secant if the inverse cosine can turn a point into a line. And the cosine of the inverse secant turns that pine back into a point.
@@jeffthevomitguy1178 How? How do you operate on points? By multiplication, exponents? What is the meaning or solution to any number operating on a point. As an example what is 3 times a circle or square? 3 circles, 3 squares? Cosines and secants have geometric meaning in 2 dimensions. Points are 1 dimensional. Points have no "shape". Even though we think of a line as a shape, what its made of (points) isn't a shape. One point doesn't make a line, but two points joined together do? How? How are they joined? Lines joined by angles give 🔺️, squares ⬛️, and polygons. How are points joined to make lines? By knots 🪢? Can we even have a visual reference? Atoms are joined together by the bonding of the outermost shells of electrons. Protons and neutrons are joined together by the strong nuclear force. Are points joined together by nuclear forces?

When we were at primary school, teacher doesn't explained how does pi value comes 3.14. amazing thanks Luke

If my math teacher explained pi this way I would have "gotten" it immediately. You're amazing.
just for that circle? or all circles?
@@jamescollier3 What?
@@jamescollier3 it’s a ratio, so yes for all circles.
@@jamescollier3 all circles because the diametre is always fit into the perimitre 3.14 times try it if u dont believe me
You’re so Amazing !!!
Thank you sooo much !!! Now I fully understand Pi and will never forget it !!!
Nice work never got into math I just am terrible at it so never learned this. Often wondered why it was this number well now I know.
When I finished watching this video, it was 3:14 am. Kinda freaks me out a bit, but also realized I should go to bed. lol
For me it was 19:47, which if you take the ln of, you get 2.97 which is basically 3, aka basically pi
@@JVerde853 That's freaky. 😁
Awesome 😍

Help a lot,,, thanks
Because the string has an ending i.e. it is finite - should not the value of pi end eventually.
Wow 👍 nice
This was my true calling
🤣🤣🤣
when they say technically
I don't know if they want to say theoretically o practically
Pi is a multiplicity of surfaces. That's why it seems to go on forever.
it doesn't seem to, it actualy does
Wait .......isn't π the integral of e to the -x² from negative infinity to positive infinity squared?
It is
He is just explaining from simplicity perspective or the basic of it ,,,you have gone too far to some other expressions of pi
...INTERESTING PRESENTATION. But the string remainder should be one-tenthish of the unit lengths. That was not the case in the video. But the strategy was sound. Cheers
We all know that pi is irrational.
*Then why its definition is a ratio?*
because one of those values in the ratio is always itself irrational. Rational numbers are expressed as a ratio of two _integers_
If you complete the circumference with all the string and there is no gap, Then why does it matter how many radiuses you fit around the circumference of a circle?
If you enclose the circle then who cares what the ratio of radiuses to circumference is.
Essentially, it's because this ratio allows you to compute the area or perimeter of any circle. If you know radius or diameter, you can know the perimeter of the circle.
it's also a special value that has many applications other than finding circumference or diameter, mainly related to curves and angles.
Dope 👍
WITH PRACTICAL; STUDENTS CAN EASILY UNDERSTAND. THANK YOU
Stop yelling your post in all caps.
Did well with the "3" part but the remainder doesn't look like ".14" at all.
yeah, he definitely pulled the string much tighter when he did the diameters than when he made the circumference. That was about .25 left over.
Close enough
@@jovmml its .14 of all three strings
It's an approximation which is much close to 3.14
@@creamu2roblox -- No, it's *not* "close enough!" The percent error is too big with the way he did it.
Ya
then why is half a circle one pi?
@Channel Good Stuff because for angles by convention we normalize by radius R which is 1/2 the diameter. C/ R = 2pi
Thanks for an interesting question. This video shows that the circumference of a circle comes from the diameter going around the perimeter 3.14 times (or pi). They used an equation of pi = c/d: another way to say this is D x Pi = C or a full circle.
Half a circle would only use have the diameter or one radius (2 radius make a diameter)
Diameter=D
Radius= R
Circumference =C
Pi= 3.14........
Full Circle. (D x Pi = C) or (R + R x P=Ci) or (2 x R x 3.14)
Half a circle (D/2 x Pi) or (R x Pi)

hold the phone, this is 7th grade stuff? And is meant to be used BEFORE algebra?? ive learned algebra before Pi in 8th grade.
355 videos 366 subscribers😢.... What a tragedy
Looks more like 3.3
I'm disappointed with my self , took me 26 years of living ,eating,shitting,sleeping to ask my self this question on 1:33 AM (what is PI why is it 3.14)
It's cause we're living in a simulation 😅
math says "infinite", reality says "finite". Wt.... ???
pi does not equal infinity, it just has infinite digits
My teacher didn't tell me about this
Ratio
The reason why we cannot solve pi is because a circle isn't 2 dimensional, it's actually 3.
