Answer:

Step-by-step explanation:
GIVEN: A right circular cone that has a height of
cm and a base with a diameter of
cm.
TO FIND: Volume of cone.
SOLUTION:
radius of cone 
height of cone 
Volume of cone 
putting values we get
Volume of cone 

Hence the volume of cone is 
i know a triangular prism has 5 faces and six vertices if that helps
The two points have the same y coordinate, which means that the line is horizontal, which means that the slope is 0.
So, the equation is y=4
First we solve for y₁
3×5 - 5y₁ = 20
15 - 5y₁ = 20
-5y₁ = 20 - 15
-5y₁ = 5
y₁ = -1
(5, -1)
Now we solve for x₂
3x₂ - 5×2 = 20
3x₂ - 10 = 20
3x₂ = 20 + 10
3x₂ = 30
x₂ = 10
(10, 2)
