Answer:
37.68 ft^3
Step-by-step explanation:
The parameters used in describing a cone is radius and height
Hence 
Radius= 3ft
Height = 2 ft
The volume of a cone is given as

substitute

Hence the volume is 37.68 ft^3
 
        
             
        
        
        
Answer:
Option 4:  y > 2x
                 x + 2y < -8
Step-by-step explanation:
Taking first equation:
 y > 2x
Putting x = 0
 y > 0
Putting y = 0
 0 > x
So the blue line in drawn according to first equation.
Taking second equation:
  x + 2y < -8
Putting x = 0
  2y < -8
y < - 4
putting y = 0
  x < -8
So the red line is drawn accordingly.
