Answer:
A two-column proof uses a table to present a logical argument and assigns each column to do one job, and then the two columns work in lock-step to take a reader from premise to conclusion.
Step-by-step explanation:
Basically in simple terms, one side is the statements, and the otherside is the reasoning

1)
The formula for calculating the cone volume is: 

Data:
V (volume) = ?
h (height) → h = 12 in
d (diagonal) = 9 in , if: d = 2*r , soon: 9 = 2*r → 2r = 9 → r = 9/2 → r = 4.5 in
Use: 

Solving:





2)
The circle area formula is: 

Data:
A (area) = ?
d (diagonal) = 19 Km , if: d = 2*r , soon: 19 = 2*r → 2r = 19 → r = 19/2 → r = 9.5 Km
Use: 

Solving:




3) False, because it's the volume, the number of cubic units needed to fill a space. 
 
        
        
        
Answer:
the tree is 8.8 m tall
I can't draw it but it will be two similar acute triangles. The one that represents the man will have a 2m height and a 5m base. The one that represents the tree will have an 8.8m height and a 22 m base.
Step-by-step explanation:
it's a proportional relationship
5/22=2/height
5(height)=2(22)
5(height)=44
divide both sides by 5
5(height)/5=44/5
height=8.8 m
