Nataly [62]

Answer:

≈ 6360 m³

Step-by-step explanation:

Volume of a cylinder = πr²h

radius = 12 m,  h= 42.2 m

Therefore;  V = 3.142 × 12² × 42.2      

                      = 19093.3056 m²

Since the tank 1/3 full of water;

Volume = 1/3 × 19093.3056 m³            

                = 6364.4352 m³            

                  ≈ 6360 m³
