The diameter of the attic is 18ft and its height is 18ft. what's is the volume of the space in the attic

I attached an image with the complete question.

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 :)

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.
