Hopes this helps:
You can just download this app that I use when I need help on a problem it it called Cymath.
<span>Displacement is closely related to the volume of each cylinder. The radius should be squared and multiplied by Pi (3.14) and then multiplied by the height of the cylinder to calculate the volume of each cylinder. This value can then be multiplied by the number of cylinders to find the total displacement.</span>

Answer:

x | y
10 1 = 1/2 (10) -4=5-5= 1
-2 -5 = 1/2(-2)-4=-1-4= -5
4 -2 = 1/2(4)-4=2-4= -2
-8 -8 = 1/2(-8)-4=-4-4= -8
