I am having a problem with ch10 problem #25. The problem says:A spherical ballon has a radius 7.35m and is filled with helium. How large a cargo can it lift, assuming that the skin and structure of the balloon have a mass of 930kg? Neglect buoyant force on the cargo volume itself.

Which equation do I use?" "Do I need to find the volume first using V= 4/3 pi(r^3)
then do I use weight or work to find how much cargo it can lift.
What is the volume of the balloon?
What is the weight of the air displaced by that volume?
What is the weight of the helium filling that volume?
If this doesn't lead you to a solution, send me your answers to these questions and I'll give you additional hints.
