Answer:
76302 grams
Step-by-step explanation:
Diameter of the balloon = 9 m
Density of the gas (weight occupied per m³) = 200 g per m³
Volume of the spherical balloon = [tex]\frac{4}{3}\pi r^{3}[/tex]
Here r = 4.5 m
Then V= [tex]\frac{4}{3}\times\ 3.14 \times (4.5)^{3}[/tex]
V = 381.51 m³
Total weight = Total volume occupied * Density
= 381.51*200 = 76302 grams.
