Answer 1

You can answer this without a calculator.

When looking at sqrt(83), find the two closest perfect squares on either side of 83.

83 is closest to 81 and 100.

Since 83 is closer to 81 than 100, and sqrt(81) = 9,
sqrt(83) is closest to 9.

Answer 2

9.11043 ( whole number 9)

This is closes to the whole number 9.
