a=18 , d =?10,n,=12
I hope this is the answer
 
        
             
        
        
        
The diameter is 6 feet, so the radius is 3 feet.  
The formula to solve for the areas of a circle is 
A = πr^2
So, A = (3.14)(3^2)
A = 28.26
Since the table is cut in half, divide the total answer by 2
A = 14.13
