Aspherical balloon has a radius of 7.05 m and is filled with helium. part a how large a cargo can it lift, assuming that the skin and structure of the balloon have a mass of 940 kg ? neglect the buoyant force on the cargo volume itself. express your answer using two significant figures.

Explanation:

= Density of air = 1.225 kg/m³

= Density of helium = 0.1718 kg/m³

r = Radius balloon = 7.05 m

Mass of skin and structure of the balloon = 940 kg

Volume of balloon

Mass the balloon can carry is given by

The mass the balloon can carry including the weight of the balloon itself is 1545.84807 kg

The mass of cargo it can lift is
