That's just the way it worked out. Pi is the ratio of the circumference of a circle to its diameter, and it just worked out that this ratio is an irrational number.
It is 3:1. This is because volume of a cone is pi/3*r*r*h while vol of a cylinder is pi*r*r*h.
Pi is an irrational number. A rational number is one that can be expressed as a fraction (or ratio), e.g. 1/3. There are fractions that are near Pi, for example: 22/7 = 3.142857 (PI = 3.14159265...) A closer fraction is: 355/113 = 3.14159292 However whatever fraction you have, you will never get exactly PI. Hence it is irrational See the links for proofs that pi is irrational.
Pi, the numerical value of the ratio of the circumference of a circle to its diameter.
First of all you need to understand how did Pi come up. consider a cake that you bought and then you cut it in 7(or more) diameters. Then you take those separate "pastries" and then arrange such that it represents like a crocodile teeth. (Trying my best to graphically represent it:) VAVAVAVAV.. Q: Now what is a circumrence? A: diameter times pi. the circumfrence(C) of the circle is represented here in dots(..) .................... :VAVAVAVAV: `````````` so C= p*d (p=pi) therefore, p=C/d Hence, Pi is nothing but a ratio (that is a fraction) And the ratio of the dots above(circumference) to the sum of the V's and A's lengths is never perfect. Hence it is irrational.
Pi is a unitless number, not a distance. Pi is a ratio it has no dimensions. Pi is the ratio of the circumference of a circle to its diameter.
There are no degrees in pi, it is a ratio.
Because the ratio of the circumference of any circle to its diameter is pi.
There is no direct ratio. The area is related to the square of the radius by the factor "pi." A = (pi) r2 (Pi is about 3.1416)
Pi is the ratio of circumference to diameter. C/d=pi always!!!
C = pi x D is the ratio of a circle's circumference to its diameter.
In a circle Pi it the ratio of the circumference to the diameter. That is to say, if C is the cirumference and D is the diamter of any circle, we have: Pi=C/D
Pi is caused by the ratio of a circle's circumference to its diameter.
The value of pi in a circle is: circumference/diameter
Pi is the ratio of the circumference of a circle to it's diameter,
Pie is not a ratio
The ratio is 1/pi.
