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

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

the expected value of the random variable : 0, 1 and 2
