Figure out the difference between his start $ and the end $ then divide 2800 by 4.4 and multiply the sum till you get the difference from the first part 
 
        
                    
             
        
        
        
Answer:
The circle's diameter is 6cm
Step-by-step explanation:
A = 28.26 cm^2
D = ![\sqrt[2]{\frac{A}{\pi } }](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B%5Cfrac%7BA%7D%7B%5Cpi%20%7D%20%7D)
D = ![\sqrt[2]{\frac{28.26}{\pi } }](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B%5Cfrac%7B28.26%7D%7B%5Cpi%20%7D%20%7D)
D = 6cm
 
        
             
        
        
        
Another word for elasticity is also called D: responsiveness
        
             
        
        
        
Area of triangle = <em>A(t) </em>= 1/2(base x height)
Area of square = <em>A(s) = </em>base x height
<em>A(s) </em>= 2 x 2 = 4
<em>2(A(s))</em> = 2(1/2(2)(2) = 2(1/2(4)) = 2(2) = 4
Add the two areas together
4 + 4 = 8
8 units² is your answer
