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.
Three
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.

1470
It is 9680
1,782,739 rounded to four significant figures is 1,783,000.
When the value 4,449 is rounded to two significant figures the number should be reported as 4,400
1050 contains 4 significant digits and cannot be rounded to two significant figures without changing the value of the number.
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.
