Josiah has a mass of 75 kg and wants to know how many helium-filled balloons it would take to fly. The density of helium is about 1 kg/m^3 less than regular air, which means a cubic meter of helium can lift about 1 kg. Fully inflated, a balloon has a diameter of 0.3 m and can be modeled as a sphere. He neglects the mass of the balloon in his calculations.
About how many balloons would it take to lift Josiah?
A. 660 Balloons
B. 1120 Balloons
C. 4750 Balloons
D. 5310 Balloons
