Suppose a new airship Star of Balogna will have the shape of a cylinder 100m long, with a radius of 15 , and will weigh 9550kg without any gas inside it. Suppose also the average passenger weighs 79kg.
Calculate how many passengers the Balogna could carry if it were filled with hydrogen, and also if it were filled with helium.
Hydrogen = 0.09kg/m^3
Helium = 0.18kg/m^3
