I know that pi is infinite, but why couldn't we calculate pi so we could find the exact area of a circle?

I basically mean why is pi infinite? Why wouldn't it end once we could use it to find the perfect area of a circle?

Pi is not infinite.  It is a finite number between 3 and 4.

It cannot be written as a fraction, and thus if you write a decimal expansion for the number, that decimal expansion will never end or repeat.
