estimate
The exact value of pi is the ratio of the circumference of a circle to its diameter. It cannot be printed exactly in numbers.
It cannot. It can only show square roots which represent only a small proportion of irrational numbers.
No. An irrational number is one that does not repeat or finish, and a calculator cannot display millions of digits like an irrational number would have.
answer
Scientists must sometimes rely on estimates when they cannot obtain exact numbers :)

Logic, observation and mathematics. Logic for figuring things out, observation for noticing things, math for getting exact numbers.
No. In fact, a number cannot be both rational and irrational; they're mutually exclusive concepts.
There is no "exact". It is infinite.
That is the correct spelling of "exact" (precise, accurate).
The exact numbers cannot be assured but as per the report to congress there were almost 610,042 homeless people in America in January 2013.
There are two main situations in which you would estimate:when there is no analytical solution and the only way is to estimate a solution using iteration,when an exact answer is not required or the time or effort required to obtain an exact answer cannot be justified by the improved precision.
"Approximately exact" is an oxymoron. An answer can be approximate or it can be exact but it cannot be approximately exact.
