Spherically shaped balloon has a radius

Reference no: EM13664213

A spherically shaped balloon has a radius of 8.56m, and is filled by helium. How large a mass of cargo can it lift, assuming that the skin and structure of the balloon have a mass of 988kg? Neglect the buoyant force on the cargo volume itself. The density of air is 1.29kg/m³ and the density of helium is 0.179kg/m³.
