Since the base of the pool is a circle with diameter 12 feet, its shape is a cylinder with radius 6 feet. As we know the volume of cylinder is given by the formula.
+V+=+%28Pi%29%2AR%5E2%2AH+ where H = 4 feet is the height of cylinder.
+V+=+%283.14%29%2A%286%29%5E2%2A%284%29+
V = 452.16 cubic feet.
Answer:To fill this pool we need 452.16 cubic feet water.
