A tower has a cone-shaped attic. The diameter of the attic is 18 ft and its height is 18 ft.

 

What is the volume of the space in the attic? Use 3.14 for pi.

Volume of a cone  =

 

(1/3) (3.14) (diameter /2)^2  (height)

 

(1/3) (3.14) (18/2)^2 (18)  =

 

(3.14/3) * (9)^2 (18)  =

 

3.14 *  81  * 18/3   =

 

3.14 * 81 * 6  ≈    1526.04 ft^3
