Out of all the measurements used in the calculation, find the one with the least number of significant digits. This will be the limiting factor of how many significant digits the answer should have.
Five. If you write numbers representing the numbers in a calculation or an answer, then the number of significant figures is the number of figures written down. The number of significant figures in 351.739002 is 9; Don't confuse "significant figures" with "decimal places". The number above has 6 decimal places.

There should be 3.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
It should have three.
That depends on the context in which it is found, or the calculation(s) involved. It should have no more significant figures than the value with the least number of sig. figs.
