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
- Step 2: Find the volume of the pool
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)
