Answer: the volume of the water in the bottle is 863.5 cm³
Explanation:
Since the water bottle is cylindrical, we would apply the formula for determining the volume of a cylinder which is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the water in the cylindrical bottle.
π is a constant whose value is 3.14
From the information given,
Radius = 5 cm
Height = 22/2 = 11 cm(because it is half full)
Therefore, the volume of the water in the bottle is
3.14 × 5² × 11
= 863.5 cm³
