Answer: -0.6
Step-by-step explanation:
The equation that best represent the volume of the cylinder in cubic inches is V = π4²h.
<h3>What is a cylinder?</h3>
A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
The volume of a cylinder is expressed as;
V = π × r² × h
Where r is radius of the circular base, h is height and π is constant pi.
Given that;
- Diameter d = 8in
- Radius r = d/2 = 8in/2 = 4in
- Height = h
- Volume of the cylinder V = ?
V = π × r² × h
V = π × (4)² × h
V = π4²h
Therefore, the equation that best represent the volume of the cylinder in cubic inches is V = π4²h.

You can multiply either the top or bottom equation by -1 so lets say you apply it to the bottom equation it’ll look like this:
-9x + 9y = 18
6x - 9y = 12
then the +9y and -9y will cancel out
-9x = 18
6x =12
then you add the two equations together
-3x = 30
divide both sides by -3
x = -10
i can't really see the image but i'm sure it's pretty cool (:
