Answer:
36.08
Step-by-step explanation:
Side DE is the side adjacent to ∠D.  Side DF is the hypotenuse of the triangle.  Adjacent/hypotenuse is the ratio for cosine; this gives us the equation

To solve this, multiply both sides by 55:

 
        
                    
             
        
        
        
The answer is 336.96. The are of a circle is A=3.14 * r^2. When you plug in your radius (12) you get 449.28. you then multiply the answer you just got with 0.75. Which gets you the answer 336.96. round if you need too <span />
