2. About how many gallons of water does the water cooler bottle contain? (1 ft3 = 7.5 gal)

Answer:
The bottle can contain 4521.6 gallons of water.
Step-by-step explanation:
Given:
The diameter of the cylindrical bottle = 16 feet.
And the height of the cylindrical bottle = 3 feet.
(1 ft³ = 7.5 gallons)
Now, to find the gallons of water the bottle can contain.
So, we find the radius first:
Radius (r) = =
Height (h) = 3 feet.
Now, to get the volume of bottle which is cylindrical in shape by putting formula (using the value of π = 3.14):
Thus, getting the volume of pool 602.88 feet³.
As, given 1 ft³ = 7.5 gallons.
Now, to get the gallons of water the pool can contain we multiply the volume of pool by 7.5:
Therefore, the pool can contain 4521.6 gallons of water.
