There is no exact value of pi. It goes on forever. But if you round it, it would be 3.14159265. An estimate of pi is 22/7, or 3 and 1/7.
Like said earlier there is no exact value but if you are dealing with fractions use 22/7 but is you are sing decimals use 3.14 or the pi key on your calculator

Exact value of pi to 10 decimal places?
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.
Could you find the circumference of a circle using the exact value for pi?
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.

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 circumference and area of the circle 6.5. Give the exact value and then use pie 3.14 for an approximation?
The question is not sufficiently specific: it does not say whether the 6.5 refers to radius or diameter. I shall assume it is the radius. The exact value of the circumference is 2*pi*r v= 13*pi units and the exact value of the area is pi*r2 = 42.25*pi square units. Since pi is an irrational number there is no decimal or fractional value that is exactly equal to pi so the above are the only possible exact values. Using pi (not pie) = 3.14, these give circumference = 40.82 units and area = 132.67 square units.
