Answer:
x = 19, y = -5
Step-by-step explanation:
x + y = 14 => x= 14-y
2x + 4y = 18 => 2(x+2y)=18 => x+2y=9
x+2y=9 => (14 - y) + 2y = 9
14 + y = 9 => y = -5
x + (-5) = 14 => x=19
The volume of the shape
We have a cylinder that is cut into two. Its external radius is 5ft, while its internal radius is 4ft.
External radius = internal radius + thickness

Internal radius = 4ft (given)
Recall that the volume(V) of a full cylinder is:

Since the cylinder is cut into two, the volume(V) is:

height (h) = 12ft (given)
The volume of the shape:
