There is an exact value - we just can't write it in numbers.

1/sqrt(3)
Because 22/7 is the approximate value of pi as a fraction but the exact value of pi has never been determined.
1.25
Everybody who gives a numerical answer to a sum involving π. The exact value cannot be calculated and so approximations must be used.
Pi is a number. Its exact value is a really long string of decimal, but it is commonly abbreviated to 3.14.
Pie is sweet and 3.14
the value of pie is ALWAYS 3.14 The deliciousness of pie gives it it's value. In mathematical terms, pi is the ratio of the circumference to the diameter of a circle.
No
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.
