You are shipping barrels of oil. The density of the oil you are shipping is 0.9 g/ml. Each empty barrel weighs 13 kg and is a cylinder with diameter 2 m and height 3 m. The cost of freight per kg is 7 cents. How much will it cost you to ship 140 barrels?
---------------
Find the volume in cubic meters.
For a cylinder, Vol = pi*r^2*h
-----
0.9 g/ml = 900 kgs/m^3
Find the mass by multiplying the volume by the density, 900 kg/m^3
Add 13 kg for the barrel.
---
Multiply by $0.07, then by 140 for the cost.
