The volume of a sphere of radius r is given by
For your given conditions, the volume of 1/2 a sphere becomes
Seems to match your 2nd choice:
... 1 over 24 over 322 over 7(83)
n = number of vehicle
C = cost
Therefore,
Just input the n values to the equation and see if you will get the resulting cost C. The equation is definitely,
C = 200n + 150
