Answer:
x=20⁰
Step-by-step explanation:
The angle 6x is next to a 3x one.
And 6x+3x=180⁰
9x=180⁰
x=20⁰
 
        
                    
             
        
        
        
The formula for volume of a cylinder is:
Volume = PI x r^2 x h, where r is the radius and h is the height.
Volume = PI x 18^2 x 40
Volume = PI x 324 x 40
Volume = PI x 12,960
The exact volume would be 12,960PI cubic ft.
The decimal answer would vary depending on what value of PI is used.
