Answer: 4in
Step-by-step explanation:
Volume of a cylinder = πR²H
Volume of a cone = 1/3πr²h
πR²H = 1/3πr²h
π is very common so it could be cancelled, so the equation now becomes
R²H = 1/3r²h
3R²H = r²h
Now substitute for the values
h = 3 x 2² x 3
--------------
3²
= 9 x 4/9
= 4in.
Therefore, the height of the cone
h = 4in.
I think it would be 20
but am not sure
Answer:
8.5
Step-by-step explanation:
Solution Steps
-9.5- (-18)
The opposite of -18 is 18.
-9.5+18
Add -9.5 and 18 to get 8.5
