A tower has a cone-shaped attic. The radius of the attic is 9 ft

and its height is 18 ft.

What is the volume of the space in the attic?

Use 3.14 for pi.

A. 21

B. 6,104.16

C. 486

D. 1,526.04

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
