Answers
Answer:
a) none of these.
Step-by-step explanation:
A number's third significant figure is the digit after the second significant figure. This is true even if the digit is zero.
For example: As a result, the third and fourth significant digits of 20,499 are 4 and 9, respectively, as are the third and fourth significant figures of 0.0020499.
A number is rounded to three significant figures in the same manner that it is rounded to three decimal places. For three digits, we start counting from the first non-zero digit.
The last digit is then rounded. We use zeros to fill in any leftover spaces to the right of the decimal point. This is due to the fact that we require them to contain the right place value for the significant digits.
So, when the number 9.089 is round off at the third significant figure then it will be 9 because 0 is at third number which is less than 5.
