Answer:

6,540m³ (or 6.50×10⁶ L)

Explanation:

  • Volume of a Sphere = (4/3)πr³
  • 80% of a quantity = [quantity]•(0.8)

The volume of that sphere at 80% capacity is:

[(4/3)π(12.5m)³]•(0.8)= 6,544.98...m³

I may be wrong about the sig-figs, but I believe it is 3 due to the 12.5m... so I'm rounding it to tens place to get the answer above.
