Answer:

  • 15.4%

Step-by-step explanation:

Volume of a cylinder:

  • V = πr²h

Container A

  • r = 10 ft, h = 11 ft
  • V = π*10²*11 = 1100π ft

Container B

  • r = 7 ft, h = 19 ft
  • V = π*7²*19 = 931π ft²

After pump out the container A has the level of:

  • 1100π - 931π = 169π

Level % in the container A:

  • 169π/1100π×100% = 15.4% rounded to the nearest tenth
