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.

What is the diameter if the circumferance is 56 inches?
Just divide 56 by pi. Pi is approximate 3.14; or use the "pi" key on your scientific calculator.Just divide 56 by pi.

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)
