Answer: 16
Step-by-step explanation:
The diameter of the circle is the length of the square as well meaning the area of the square is 4 x 4 = 16
 
        
             
        
        
        
Subtract the second equation from double the first equation:
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0.  Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3.  The solution to this system is x=3, y=0, or (3, 0).
