Answer:
857.766cm^3
Step-by-step explanation:
Given data
Lenght = 3m
Internal radius r = 3m
External radius R= 10m
Volume of pipe= πr^2h
Volume of metal= External - Internal
Volume= πR^2h-πr^2h
Volume= πh(R^2-r^2)
Volume= 3.142*3(10^2-3^2)
Volume= 3.142*3(100-9)
Volume= 9.426*(91)
Volume= 857.766cm^3
Hence the volume of the metal is 857.766cm^3
15 miles because it travelled 30 miles then travelled 15 miles in the direction of the station, so 30-15=15

Step-by-step explanation:
Among the given numbers, 
We have two numbers, which are 22/7 and 
Both of the numbers are irrational numbers, they are nonrepeating and nonterminating.
A fraction written in a particular way is called decimal form.
Now, evaluating both the given numbers in decimal form, we get,
22/7 = 3.14
and 
Now, Clearly, 4.12 > 3.14
Thus,
