Answer to Problem 59A
The answer in round-off is
Explanation of Solution
The known digits plus the last, estimated digit make up the significant figures in a measurement.
The significant figures are preserved when numbers are rounded off.
Round the number to three significant figures in the measurement.
If the second digit after the decimal is greater than or equal to 5, then the 1st digit after the decimal is added up by the number 1. If the second digit after the decimal is lesser than 5, then the 1st digit is alone taken up.
In the given question, the operations are already performed. Only a round-off of the answer should be done.
