Given the weight of the hot-air balloon to be 600 lb. If the heated air inside the balloon has a temperature of 160 oF while the air outside has a temperature of 85 oF, determine the required volume of the balloon to support the weight (in ft3). Assume the inside and outside air to be at standard atmospheric pressure of 14.7 psia. If the balloon had a spherical shape, what would be the required diameter (in ft)? *Use 1 decimal place on partial and final answers.
