Different people found better and better approximations. The exact value can only be expressed as the symbol for pi; it has been proven that pi is irrational, in other words, you can't write it exactly as a fraction with integers in the numerator and the denominator. Therefore, you might say that nobody found the exact value of pi, and nobody ever will.

How do you find the circumfernece of a circle?
If you want an approximate answer, you can measure it with string. If you want an exact answer and know the radius, multiply by 2*pi to find the circumference.
What is the approximate circumference of the circle. Use 3.14 to approximate pi?
If pi=3.14, then the circumference is ( 3.14 times the diameter).
Who were the first known people to value pi?
People from ancient civilizations knew about the value of pi but as it was then as it is now the exact value of pi has never been conclusively found because it is an irrational number.
What is the exact area of the region bounded by two concentric circles with radii 10 inches and 6 inches?
You probably want the area of the donut between the two circles.The area of each circle is [ (pi) x R2 ].The area between two concentric circles is (pi)R12 - (pi)R22 = (R12 - R22)pi = (102 - 62)piThe "exact area" is 64(pi) inches2.The approximate number is 201.062 inches2 (rounded)
What is the approximate area of a circle with radius 80?
Approximate . . . [ 20,106.193 ] units2 Exact . . . . . [ 6,400 pi ] units2
Why is a fraction of pi better then the decimal of pi?
Since pi is an irrational number it is impossible to represent the exact quantity as a decimal; you can only give and approximate value. However, if you write a fraction that includes the symbol for pi, you are giving an exact quantity.
What other approximate values for Pi have been used and who discovered them?
Every person who has ever used the "value" of pi in a calculation has used an approximation.
Why the value of pie is 227?
Because 22/7 is the approximate value of pi as a fraction but the exact value of pi has never been determined.
Values to be taught through teaching of mathematics?
You can teach the value of Pi...or atleast approximate it to arbitrary precision.
What is the exact values of sin 2 pi?
2*pi is one complete revolution, i.e. 360 degrees. Sin of 2*pi = sin 360º = 0
What are some famous mathematical problems pi?
If the value of pi is the circumference of any circle divided by its diameter then what is the true exact value of pi? Why is it that the exact area of a circle can never be found?
What is the area of circle with a radius of 1.2cm?
Area = (pi * radius)^2, so: Area = (pi * 1.2cm)^2 Area = 1.44 pi cm (an exact value) If you want to approximate the area, just multiply 1.44 by pi.
What is 24 x pie?
the answer is 75.36800285107463826459265926640261836577261120365428123494831029384756 also if you want the exact form (approximate form above) it is 24(pi symbol)
What is the approximate circumference of a circle with a radius of 30 inches?
The exact answer is 2*30*pi = 60*pi Using 3.14 as an approx value for pi, the approx circumference would be 3.14*60 = 188.4 inches

How can you calculate the exact value of pi?
22 divided by 7 * * * * * That is an APPROXIMATE value of pi. The exact value cannot be calculated since pi is a transcendental number - a special kind of irrational number. It has an infinite decimal representation with no recurring pattern. That would be true in any base - binary, octal, or another base (other than pi itself, or a power of pi).
