Help please 3. Solve the following.
a) This railway car is 320 cm in diameter and 17.2 m long.
Calculate its volume of fuel it can transport in liters. [Hint: 1 m3 = 1,000 L]

138330.608 liters (about 138331)

Step-by-step explanation:

V = πr²h

r = 320 / 2 = 160cm = 1.6m

V = π * 1.6^2 * 17.2 = 138.330608 m³

138.330608m³ * 1000L = 138330.608 liters

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
