Question

At a railway yard, locomotives are used to pull containers full of oil. A locomotive is chosen according to the volume of oil it can pull as shown in the table. Consider a cylindrical container that needs pulling. It is 40 feet long and 12 feet in diameter. If one-half of the container is filled with oil, which locomotive should be selected to pull it?

Answer 1

\[V_{cylinder} = \pi r^2 h = \pi (\frac{ d }{ 2 })^2h = \pi (\frac{ 12 }{ 2 })^2*40=1440\pi \approx 4521 ft^3\]
Since you fill just one half, BR73 should do

Answer 2

thank you sir!
