Answer:
254.4 in²
Step-by-step explanation:
Area of a circle is given by the formula:

Our radius is 9 so we substitute this into the equation:
π(9)² = 81π 
81π = 254.4 in²
 
        
                    
             
        
        
        
I think you have to divide it by 10 so the new volume would be 16 square inches.
        
                    
             
        
        
        
1st number = x
2nd number = y
2x + y = 26
                    -
  x + y = 10
x = 16
26 - (2 x 16) = -6
10 - 16 = -6
Number 1 is 16
Number 2 is -6
        
             
        
        
        
Answer:
x < -2
