Wow what grade are you in that seems hella confusing!! I feel bad for you!
The choices are not attached but we can solve the problem from the given information
Answer:
The expression can be used to find h is
The height of the cone is
cm
Step-by-step explanation:
The formula of the volume of the cone is V =
π r² h, where
- r is the radius of its base
- h is the height of it
Let us find the height of the cone from the formula of its volume
∵ V =
π r² h
- Multiply both sides by 3
∴ 3 V = π r² h
- Divide both sides by π r²
∴ 
- Switch the two sides
∴
The expression can be used to find h is
∵ The radius of the cone is 7 cm
∴ r = 7
∵ The volume of the cone is 147 cm³
∴ V = 147
- Substitute them in the expression of the height to find it
∵ 
∴ h =
cm
The height of the cone is
cm
Answer: The greatest number of plates Lenin can prepare = 4
and there will be 3 chickens and 4 rolls in each plate.
Step-by-step explanation:
Given: Lenin is preparing dinner plates. He has 12 pieces of chicken and 16 rolls.
To make all the plates identical without any food left over, the greatest number of plates Lenin can prepare = G.C.D.(12,16)=4
The number of pieces of chicken in each plate = 
The number of pieces of rolls in each plate = 
So, the greatest number of plates Lenin can prepare = 4
and there will be 3 chickens and 4 rolls in each plate.
Step-by-step explanation:
H=14 in.
B1=16in.
b2=9in
Area =(16+9)*14/2=175 inches²
