Respuesta :

Answer:

[tex]44,800\ mi^2[/tex]

Step-by-step explanation:

we know that

To Round a number

a) Decide which is the last digit to keep  

b) Leave it the same if the next digit is less than [tex]5[/tex] (this is called rounding down)  

c) But increase it by  [tex]1[/tex] if the next digit is  [tex]5[/tex] or more (this is called rounding up)

In this problem we have

[tex]44,816[/tex]

We want to keep the digit [tex]8[/tex]

The next digit is [tex]1[/tex] which is less than [tex]5[/tex], so no change is needed to [tex]8[/tex]

therefore

the answer is  

[tex]44,800\ mi^2[/tex]
