Answer:

11.6

Step-by-step explanation:

Solving with steps as below:

31*r+1.1*(35−31)*r = 410.64
31r + 1.1*4r = 410.64
31r + 4.4r = 410.64
35.4r = 410.64
r = 410.64/35.4
r = 11.6

Answer is: r =11.6

A circular pool if filling with water. Assuming the water level will be 4' deep and the diameter is 20' , what is the volume of

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

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)
