Answer:
Yemen was a poor country with a government widely acknowledged to be corrupt, with a large amount of weapons in private hands. By 2011, the country was already facing challenges from al Qaeda-linked militants and separatists in the south and Zaydi Shia rebels in the north.
 
        
             
        
        
        
V = pi r^2 h
v = 3.14 * 5^2 * 15
v = 3.14 * 25 * 15
v = 1177.5 in^3
        
             
        
        
        
Answer: y=6
Step-by-step explanation:
The given number is y.
According to the question,
Step 1 . subtracts three from the number (y-3), then doubles it
i.e. Final number = 2(y-3)
Step 2 .  subtracts three again i.e. (2(y-3)-3), and doubles the number again
i.e. Final result  = 2(2(y-3)-3)
If the result is his original number y, then
2(2(y-3)-3) =y 
⇒ 2(2y-6-3)=y   [ using distributive property]
⇒ 2(2y-9)=y
⇒ 2(2y)-2(9)=y [ using distributive property]
⇒ 4y -18=y 
⇒ 4y -y= 18 
⇒ 3y= 18
⇒ y= 6    [Divide both sides by 3]
Hence,  y=6
