Answer: Option D, 
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 .
Answer:
27A+81A =108
Step-by-step explanation:
It’s the last one & the second one
If the equation is f(x)=2x+5
The domain is 2x+5
If the range is 1, the domain is 7
