First find the volume of that container
R = pi (r)^2h
R = pi (15.21)(12.4)
R = 592.5169408
60,000 / R = 101.2629275
102 storage tanks
B and C
3^3 = 27
the cubed root of 27 is 3
Part A
Your problem statement already shows you the conversion.
Bottles purchased: 5×10¹⁰
Bottles recycled: 8.3×10⁹
Part B
The ratio of bottles purchased to bottles recycled is
... (5×10¹⁰)/(8.3×10⁹) = 0.6×10¹ = 6.0
The number of bottles purchased is 6 times the number of bottles recycle.
Going 315 km uses up 35 liters of gasoline
On average, 1 liter of gasoline can travel the number of kilometers:
315 : 35 = 9 liters of gasoline
