The answer would be 24pi inches. 
You can find this by using the formula for a circumference and plugging in the value of the radius. 
C = 2pi*r
C = 2pi * 12
C = 24pi
 
        
             
        
        
        
5 and 6 because 5 1/4 = 5.25.
5.25 is less than 6, but greater than 5.
        
                    
             
        
        
        
Answer:
28
Step-by-step explanation:
area = width x height
area = 7 x 4
area = 28 square feet
 
        
                    
             
        
        
        
The perimeter is 32
I'm having a little difficulty finding the area because I forgot how the get the height... if I knew the height I would tell you. 
I am so sorry I can not help all the way. 
but if you find the height  Area= base (11) times height (?)
        
             
        
        
        
I think the incorrect data is the second x to the left.
