For example, by calculating the surface of a circle, using an integral.
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.
The numerical value of pi is often found using a Taylor or Maclaurin series (Taylor series centered at 0).
The value of pi (Ï€) is3.1415926535897932384626433832795028841971693993751.........
No one has fully discovered pi. Pi is believed to be irrational.
Euclid discovered pi
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.

No, because pi has no exact value, it is neverending. You can get close by using 3.14, but never will you get it exactly right. Up to date, about 4 trillion digits have been calculated.
The value of Pi is 3.14 so the value of Pi by 2 is 6.28.
The numerical value of pi is often found using a Taylor or Maclaurin series (Taylor series centered at 0).

The approximate value of pi is 3.14159265.
The value for Pi for math is 3.14. Pi is the 16th letter in the Greek alphabet.
You get the value of pi by dividing the circumference with the diameter of a circle. pi = c/d
