Answer:
A ≈ 494.80
V = 827.02
Step-by-step explanation:
height ( <em>h </em>) = 13 mm
radius ( <em>r </em>) = = 4.5 mm
Surface area =
= 2π(4.5)(13) + 2π(4.5)
≈ 494.80
Volume =
<em> </em>=
= 827.02
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 .
