Answer:

Explanation:
You are comparing irrational numbers.
By inspection, i.e. at first sight you can only compare
because they have the same radicand.
You can order: 
You can introduce the 2 inside the radical by squaring it:

Since 5 is between 3 and 12, you can order:
Which is:
You must know that π ≈ 3.14.
5 is less than 9 and the square root of 9 is 3; hence,
and 
Now you must determine whether π is less than or greater than 
Using a calculator or probing numbers between 3 and 4 you get 
Hence, the complete order is:
The circumference of circle with a radius of 63mm is 395.84
I hope this helps!
Answer:
The radius of the base is 
Step-by-step explanation:
we know that
The volume of a cone is equal to

we have



substitute and solve for r


![r^{2}=864/[(3.14)(7)]](https://tex.z-dn.net/?f=r%5E%7B2%7D%3D864%2F%5B%283.14%29%287%29%5D)

you would have to do 170/20 which equals 8.5 multiply that by 8
so his daily does would be 510 milligrams
