Fbuoyant = (density)(gravity)(volume)

density = 1.29

gravity = 9.81

volume = 4*π*r3 / 3 = 0.003729


hence; Fbuoyant = (1.29)(9.81)(0.003279) = 0.047192 N

can you please help me solve: an airplane has a volume of 124 m^3. how much buoyant force does the air exert on it? assume the air density remains 1.29 kg/m^3

Same as previous post. Change the the volume. F = 1.29 * 9.81 * 124 = 1569.2 N
