Because, to two significant figures, the value of 2,974894956..... is rounded off to 3,0The question was posed with three significant figures so you could argue that the answer should be 2,97.
The rounded value is 10. See also the links below. * * * * * However, there is no such thing as the correct number of significant figures (sf). SF depends on the context as well as the SF of the numbers used to compute the value.
Five significant figures.
There are five significant figures in the given value. It is according to the rule of significant figures which say that zeros right to the decimal point are significant and all non zero digits are significant So , all the digits in the given value are significant figures i.e 5 significant figures.
As trailing zeros after a decimal point are not normally written, for them to be written means they must have significance, so 4.270000 has 7 significant figures (it may have been rounded from 4.2699995 to 7 sig fig). 4.27 (the same value) would only have 3 sig fig.
When the value 4,449 is rounded to two significant figures the number should be reported as 4,400
1,782,739 rounded to four significant figures is 1,783,000.
1470
1050 contains 4 significant digits and cannot be rounded to two significant figures without changing the value of the number.
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.
9,682 rounded to three significant figures is 9,680.

If you are rounding a 4 digit number to 3 significant figures, then you're rounding to the nearest ten. The 4th digit is 7, so since this digit is >= 5, you should round up the 3rd digit. 1467 becomes 1470. In scientific notation you would express this as 1.47 x 103 to make it clear that there are only 3 significant figures.

The value 10.00 has _____ significant figures.
The percent error in the measurement of density is calculated by taking the absolute difference between the measured value and the accepted value, dividing it by the accepted value, and then multiplying by 100. The result is rounded to the appropriate number of significant figures.
When performing a logarithmic calculation involving significant figures, the number of significant figures in the result is determined by the number of decimal places in the original values being used in the calculation. The result should be rounded to match the original value with the fewest decimal places.
