5.2 feet is 158 cm
5 feet, 2 inches is 157 cm
179
5 ft 10.5 inches = 70.5 inches = 70.5 * 2.54 cm = 179.07 inches which, rounded to the nearest cm is 179 cm.

When rounding to the nearest 10th, you are looking at the first decimal place. In this case, 1009 is a whole number, so there are no decimal places to consider. Therefore, when rounding 1009 to the nearest 10th, it remains 1009 without any change.
The answer will depend on the degree to which the number is rounded. Without any indication of that, it is not possible to answer the question sensibly.
