Welp, looking at the number: 66
......
The second digit "6" is up to or more than 5.
...............
So, we can clearly round it up.
.....................
In this case, we are rounding to the nearest hundredth.
.............................
Hm, 100 is pretty close to 66.
..................................
We can now say that the nearest hundredth is 100.
...............................................
BAM! *drops mic*
It is 10.2 centimeters so option A :)
It is the same. Even though you put a 0 in the end can't change the number
The answer is either 4 or 8 I do believe
