<u>Answer:</u>
Piston displacement = 84.8
<u>Step-by-step explanation:</u>
We will find the volume of the cylinder in order to find the piston displacement.
Here, (bore = diameter, so r = diameter/2) (height = stroke)
Volume =
= 21.2 cubic units
Since the engine has 4 cylinders, so we will multiply the piston displacement by 4 to get:
Piston displacement =
= 84.8

Step-by-step explanation:
Answer:
x = -1, y = 4
Step-by-step explanation:
x + y = 3
-x + y = 5
This means that y = 3 - x
We can substitute this value into the equation
-x + y = 5
-x + 3 - x = 5
3 - 2x = 5
Subtract 3 from both sides
-2x = 2
Divide both sides by -2
x = -1
Plugging this number into the equation, we have:
-1 + y = 3
Add 1 to both sides
y = 4
