we have  which is a cubic function.
 which is a cubic function.
and  .
.
from f(x) and g(x) we know that both are cubic and g(x) has shrink of 1 and up by 4 units in x axis .
 
        
                    
             
        
        
        
Answer:
Hence the new height  is 3 times the original height .(h1=3h)
Step-by-step explanation:
Given:
A cone with  has height and base with radius r .
To Find:
What is new height 
Solution:
Consider as cone with height h base radius r, and volume v
Here given that only height changes for the cone  i.e. r remains the unchanged or same or constant 
The volume for a regular cone is given by ,

Here V is directly proportional to h i.ee pie ,3 and r being constant 

i.e V/h=constant
V1 and h1 are new dimensions for new cone
V/h=V1/h1
Here V1=3V
So V/h=3V/h1
1/h=3/h1
i.e  h1=3h
Hence the height  is 3 times the original height .
