The exact value of pi is the ratio of the circumference of a circle to its diameter. It cannot be printed exactly in numbers.
Pi is an irrational number, meaning that it cannot be written as the ratio of two integers (fractions such as 22/7 are commonly used to approximate pi; no common fraction (ratio of whole numbers) can be its exact value).
If you have a circle ... any circle ... and you measure its circumference, measure its diameter, and divide the circumference by the diameter, the answer is always the same number, which people have decided to label with the name "pi". "Pi" is the ratio of a circle's circumference to its diameter, but "pi" is not a rational number, since it's not the ratio of any two integers.
It is pi because a circle's circumference divided by its diameter is the value of pi which is an irrational number that can't be expressed as a fraction.
The term pi refers to the ratio of a circle's diameter to its circumference. The actual value is a transcendental number, that is, a number whose decimal value "keeps going to infinity" and does not repeat. As such, pi has no "full form" unless we choose to just write the symbol, which means "exactly the number" which is the ratio of a circle's diameter to its circumference. That's as "full" as we can make it. In other words, pi does have an exact value, but that value can not be expressed numerically.
The value of pi in a circle is: circumference/diameter
Any circle's circumference divided by its diameter has a value of pi
the value of pi can be derived as the ratio between the circumference and diameter of every circle, say pi = circumference/diameter
The exact value of pi is the ratio of the circumference of a circle to its diameter. It cannot be printed exactly in numbers.
3.14 is the approximate value of pi.
Specifically geometry. Pi is the numerical value of the ratio of the circumference of a circle to its diameter.
The value of pi is an irrational number. Pi is the ratio of the circumference of a circle to the circle's diameter. Also, π is a transcendental number.
It is unknown and it usually just represented as pi. It represents the ratio between the circumference and the diameter.
Pi is the ratio of the circumference of a circle to the diameter. Thus for any circle, if you divide the circumference by the diameter, you get a value close to pi.
In math terms, pi, means 3.14, which is a everlasting decimal, that is just rounded to make your math easier. So pi, means 3.14 in math terms.
Pi is the ratio of the outside circumference of a circle (perfect) to the radius expressed in the equation Pie are Squared ;) (Pi X R2) Pi is the value of Pi and R is the Radius of the circle.
The word and symbol for pi comes from the Greek alphabet and it was discovered, not invented, by ancient mathematicians who discovered that there was a ratio relationship for any circle that its circumference divided by its diameter is nearly about 22/7. But the true value of pi still remains undiscovered because its decimal place value runs into infinity with no ending in sight.
