There are four significant figures in the measurement 77.09 meters. Each non-zero digit and any zeros between them are considered significant.
It depends upon how you got to the 12, for example: 28.6 - 16.6 = 12.0 Because each of the numbers that was used to get to the 12 had 3 significant figures, you should write the 12 with three significant figures also. However: 29 - 17 = 12 In this case, each of the numbers that was used to get to 12 had only 2 significant figures, so use only 2 significant figures in the 12.
4 of them.

The appropriate number of significant figures to use in expressing the result of 51.6 x 3.1416 is three. This is because the factors each have three significant figures, so the result should also have three significant figures. The answer would be 162.
