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.
The longest known value of pi is now into the hundreds of billions of digits.

Probably one of the 'what is the value of Pi to x decimal places' answers, stretching to millions of digits. These helpful answers are of great value to us
The value of Pi is 3.14 so the value of Pi by 2 is 6.28.
There can be no "closest" value. The area is pi*r^2 Using pi = 3.14 gives the area as 28.26 sq inch Using pi = 3.14159265358979 (Excel default), gives the area as 28.2743338823081 sq inches which will be closer to the true area. The value of pi has been calculated to over 10 trillion digits and each additional digit in the value of pi gives a value for the area which is closer to the true value. . And, the value of pi can be calculated to still greater accuracy which would give a closer answer.
