Yuliya22 [10]

35,569.92 L of water is required to fill the pool

Step-by-step explanation:

  • Step 1: Find the area of the circular pool when radius = 20/2 = 10 ft

⇒ Area = πr² = 3.14 × 10² = 314 ft²

Volume = Area × Depth

             = 314 × 4 = 1256 ft³

  • Step 3: Convert the volume into liters.

Volume of water = 1256 × 28.32 = 35,569.92 L (∵1 ft³ = 28.32 L)
