First you would find that not all the units are the same in this problem, so you convert yards to feet. So 4 yards = 12 feet. 
The proportion you would make would be x/12 = 2/1
        
                    
             
        
        
        
Answer:
12.96pi
Step-by-step explanation:
area = r^2 *pi
= 3.6^2 * pi
= 12.96pi
 
        
                    
             
        
        
        
Answer:
26.69 square meters 
Step-by-step explanation:
A=r(3.14)
A= 8.5(3.14)
A=26.69 meters 
 
        
             
        
        
        
Rate of change=(changespeed)/(changetime)=(s1-s2)/(t1-t2)
change is (0-60)/(0-5)=-60/-6=12
answer is 12 units per second
        
             
        
        
        
The correct answer here would be D. And that is because, in a triangle, the sum of 2 of the sides has to be greater than the third side for all sides.  If we add 22 and 13 we get 35, and 35 is greater than 9, for sure. But if we add 13 and 9 we get 22 which is not greater than the third side length of 22; it would be collinear with the side length and it has to be greater than the side length.
