Answer:
50.24
Step-by-step explanation:
Area=R^2*PI
OR
Area-R*R*PI
So, Area=4*4*3.41
=50.24
 
        
                    
             
        
        
        
First, find the GCF. For these two numbers, it is 36. (Because 36 times 1 is 36 and 36 times 2 is 72)
Divide both sides by this, which gives you a 
2:1 ratio
        
                    
             
        
        
        
Pretty sure the answer is k
