Answer:
The water tank carries approximately 155,346 liters of water.
Explanation:
The volume of a cylinder is given by the formula V = πr^2h.
V = π(2.1m)^2(4.5m) = 49.5π m^3
Therefore, the water tank has a volume of 49.5π cubic meters when full.
1 m^3 = 1000 L.
49.5π m^3 × 1000 L/m^3 ≈ 155,346 L
Therefore, when full, the water tank carries approximately 155,346 liters of water.
