Answer:

4.89897948557


if you rounded it, it would be 4.90, or 4.9

Explanation:

First, I solved 3.14 x 11.7. This gave me 36.738.


Next, I did 885 divided by 36.738. This gave me a long list of numbers, but the whole was 24. (24.0894986117916…)

I rounded that number to 24.

Now, I found the square root of 24. Square root is basically a number that is multiplied by itself to get a number. For example, the square root of 9 is 3, because three times three is nine.

Anyways, the square root of 24 came out to be 4.89897948557. So, I rounded and got 4.9.

Hope this helped you! Sorry if I’m wrong, I tried my best to answer it correctly, I’m in middle school too… so I could be wrong!!
