Answer:volume of attic = 1526.04 ft³
Explanation:Volume of cone can be calculated using the following rule:
Volume =

* area of base * height
Volume =

* π * radius² * height
We are given that:
π = 3.14
radius = 18/2 = 9 ft
height = 18 ft
Substitute in the equation to get the volume as follows:
Volume =

* 3.14 * (9)^2 * (18) = 1526.04 ft³
Hope this helps :)
