There are several different measures of average spread: the standard deviation is the most common but average absolute deviation is another possibility.
You could also have total ranges or inter-quartile ranges from sets of observations, each one being a measure of spread. Their averages would also be average spreads.
You would have to calculate the average spread according to whichever definition you wanted and then round up or down to 2 decimal places (or the nearest hundredths).

Round your answer to two decimal places. Example: Your calculator's answer is 2.133334442 You round to: 2.13
To find the height of a parallelogram, you divide the area by the base length. So in this case, the height of the parallelogram would be 115/12 = 9.58 to the nearest hundredth.
If you have the radius, then area = pi*r2 which you then round to the nearest hundredth. If you do not know the radius but do know the diameter or circumference, you can calculate the radius. Otherwise you need to measure it.

You find the hundredth place then look at the number behind it. If its greater than 5, round up. If not, round down
16.6 x pi = 52.15 to the nearest hundredth
Sqrt(27.05) is one such number. Its decimal approximation, to the nearest hundredth, is 5.20 - but to the nearest thousandth is is 5.201

First find the length of the other leg by using Pythagoras: 112-42 = 105 Area = (4*the square root of 105)*1/2 = 20.49390153 Area = 20.49 square cm to the nearest hundredth
To find the height of a parallelogram, you divide the area by the base length. So in this case, the height of the parallelogram would be 115/12 = 9.58 to the nearest hundredth.
the square root of 16 is exactly 4 so answer is 4.00 but again it is exact and not simply nearest
