Answer: option D is the correct answer.
Step-by-step explanation:
The tower has a cone-shaped attic. Therefore, we would apply the formula for determining the volume of a cone which is expressed as
Volume = 1/3 × πr²h
Where
r represents the radius of the cone.
h represents the vertical height of the cone.
π is a constant whose value is 3.14
From the information given,
Radius = 9 feet
Height = 18 feet
Therefore,
Volume = 1/3 × 3.14 × 9² × 18
Volume = 1/3 × 3.14 × 81 × 18
Volume = 1526.04 ft³
