Step-by-step explanation:

Circumference

When you are seeing which number is bigger first you look at the first digit
<u></u>0.<u>8</u>3  or 0.<u>8</u>02
   ^8         ^8
If they equal the same, look at the second digit
0.8<u>3</u> or 0.8<u>0</u>2
     ^3       ^0
3 is greater than 0
<u>0.83 is larger 
</u>
you can also look at it this way:
0.83 = 0.830
What is bigger
0.802 or 0.830?
0.83 is bigger
