Please Help! Coefficient of Volume Expansion Question On a hot day (30^{0}C) an oil trucker loaded with 50 000L of gasoline into his truck. By the time he got to his destination the temperature has dropped to -5^{0}C. How many litres of fuel did he deliver? The coefficient of volume expansion of gasoline is 9.5 X10^{-4} /^{0}C. The coefficient of linear expansion for his steel tank is 11X10^{-6}/^{0}C. The tank is a cylinder 10m long with a radius of 2m V=V_{0}(1+3alpha [tex]\Delta[/tex]T [tex]\Delta[/tex]V/V_{0}=[tex]\beta[/tex][tex]\Delta[/tex]T i figured out the volume of the cylinder is 40pi m^{3} but i dont know where to go from there.
