Let x be the <span>heights of a maple tree and y be the height of the cherry tree.
We know: 
</span>

<span>The new ratio is obtained like this:
</span>

.
From the above equation we get 

.
then 

Solving the above equation for y we get: 

So 
 So the first tree is (400-160=240) more taller than cherry tree.
So the first tree is (400-160=240) more taller than cherry tree. 
 
        
        
        
The answer to the first part is D
        
                    
             
        
        
        
The answer is 1 over 3(3.14)(5²)(8) 
The volume of the cylinder (V1) is:
V1 = π · r² · h                (r - radius, h - height)
The volume of the cone (V2) is:
V2 = 1/3 π · r² · h         (r - radius, h - height)
It is given:
r = 5 feet
h = 8 feet
π = 3.14
Therefore, the volume of the cone is:
V2 = 1/3 · 3.14 · 5² · 8   which is the same as 1 over 3(3.14)(5²)(8).
