The exact value of pi is the ratio of the circumference of a circle to its diameter. It cannot be printed exactly in numbers.
3.1415926536 is to 10 places but not exact. The only exact value of pi is pi itself. So any exact answer involving pi would include pi in the answer.
there are infinite numbers in pi
The exact area is 625*pi. Since pi is an irrational number, any exact answer must include pi and may not contain a decimal (or rational) approximation of pi.
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).

Irrational numbers can never be expressed as fractions as for example the square root of 2 or the exact value of pi.
the formula to convert degrees to radiansangle in radians = angle in degrees * Pi / 180 .

The circumference of any circle when divided by its diameter has the exact value of pi
There is no way to find the exact area of a circle. The formula for the area is Pi times the radius squared. But Pi is an irrational number -- that is, no matter how many numbers you write it out to, you could always write it further. Since there is no exact value of Pi there can be no exact value of the area based on the diameter. The radius is half that of a diameter. Therefore, if you know the diameter you know the radius. In this case the radius is 3cm and the area of the circle = pi * 32 So the answer is roughly
The exact area = pi*32 or 9*pi square cm
Yes, you could if you knew the exact value for pi as well as the diameter of the circle. Multiply the diameter by the exact value for pi to get the circumference. However, it is impossible because the exact value for pi is not known. It is only known to about a trillion decimal places, but the exact value is not known.
