Answer: the barrel will hold 9.42 ft³ of water.
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
Radius of barrel = 1 feet
The barrel is 3ft wide. It is the same as the height. Therefore,
Volume of barrel = 3.14 × 1² × 3 = 9.42 ft³
