Answer: Volume = 254.3 inches²
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 = 3 inches
The height of the cylinder is three times the radius. It means that
Height = 3 × 3 = 9 inches
Therefore,
Volume = 3.14 × 3² × 9
Volume = 254.3 inches² to the nearest tenth.
