Three significant figures: two before the decimal point and one after.
Forget about "significant figures"; those are used to determine the precision when you multiply or divide. When adding numbers, the rule is that the result should be rounded according to the precision of the least accurate of the addents. In this case, to one decimal digit.
When adding measurements, the result should be reported with the same number of decimal places as the measurement with the fewest decimal places. In this case, 11.074 mm has three decimal places, while the second measurement is unspecified. Assuming the second measurement has no decimal places, the result should be rounded to zero decimal places, thus reported as 11 mm. If the second measurement has decimal places, adjust accordingly based on that.
No, when multiplying or dividing measurements, the answer should have the same number of significant figures as the measurement with the fewest significant figures. This rule ensures that the precision of the result reflects the least precise measurement used in the calculation. Therefore, the final answer should be rounded accordingly to maintain appropriate significant figures.
sum
When adding or subtracting measurements, the number of significant figures in the result should match the measurement with the least number of decimal places.
When adding or subtracting measurements, the result should have the same number of decimal places as the measurement with the fewest decimal places. When multiplying or dividing measurements, the result should have the same number of significant figures as the measurement with the fewest significant figures.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

When adding or multiplying numbers with significant figures, the result should be rounded to the least number of decimal places in the original numbers. For addition, the result should have the same number of decimal places as the number with the fewest decimal places. For multiplication, the result should have the same number of significant figures as the number with the fewest significant figures.
When multiplying or dividing numbers, the result should have the same number of significant figures as the factor with the fewest significant figures. When adding or subtracting numbers, the result should have the same number of decimal places as the number with the fewest decimal places.
When adding numbers, the result should be rounded to the same number of decimal places as the number with the fewest decimal places. This ensures that the final answer has the appropriate number of significant figures.
When adding or multiplying numbers, the result should have the same number of decimal places as the number with the fewest decimal places. For addition, the result should have the same number of significant figures as the number with the fewest significant figures. For multiplication, the result should have the same number of significant figures as the number with the fewest significant figures.
When adding numbers, count the number of decimal places in each number. The result should have the same number of decimal places as the number with the fewest decimal places. This final number is your answer with the correct number of significant figures.
The precision of a calculated result based on measurements is determined by the precision of the measurements themselves. The more precise the individual measurements are, the more precise the calculated result will be. Additionally, the number of significant figures in the measurements and the mathematical operations involved also affect the final precision of the result.
When adding numbers with significant figures, the result should be rounded to the least number of decimal places in the original numbers. Add the numbers as usual, then round the result to the appropriate number of significant figures.
