Question

upper bound of 4522.14 cm

Answer 1

upper bound of 4522.14 cm is as follows.

Upper and lower bounds are used to describe all the possible values that a rounded number could be.

Lower Bounds - The lower bound is the smallest value that would be used to round up a number to the previously estimated value.

Upper Bounds - The upper bound is the smallest value that would be used to round up a number to the next estimated value.

For example, 140 cm measured to nearest 10 cm.

10/2 = 5

Upper bound 140 + 5 = 145

Lower bound 140 - 5 = 135

Similarly for  

4522.14 = 1000

1000/2 = 500

Upper bound 4522.14 + 500 = 5022.14

Lower bound 4522.14 - 500 = 4022.14
