The answer is 1 over 3(3.14)(5²)(8) 
The volume of the cylinder (V1) is:
V1 = π · r² · h                (r - radius, h - height)
The volume of the cone (V2) is:
V2 = 1/3 π · r² · h         (r - radius, h - height)
It is given:
r = 5 feet
h = 8 feet
π = 3.14
Therefore, the volume of the cone is:
V2 = 1/3 · 3.14 · 5² · 8   which is the same as 1 over 3(3.14)(5²)(8).

Answer:
The area of the triangle is  
Step-by-step explanation:
Given:
Coordinates D (0, 0), E (1, 1)
Angle  ∠DEF = 60°
△DEF is a Right triangle
To Find:
The area of the triangle
Solution:
The area of the triangle is  = 
Here the base is Distance between D and E
calculation the distance using the distance formula, we get
DE  = 
DE =
DE = 
DE = 
Base = 
Height is DF
DF =
DF = 
DF = 
Now, the area of the triangle is 
= 
=
=
=
 
        
             
        
        
        
Answer:
B) x - 4
Step-by-step explanation:
In this question, you have to simplify the expression to get your answer.
Solve:
1/2(2x - 8)
Use the distributive property.
1/2(2x) + 1/2(-8)
x + 1/2(-8)
x - 4
Your answer would be B) x - 4
