We use the ratio x:360 to find portions of the circle (again, through the ratio)
so we use 60/360 = x/30 in^2
1/6 = x/ 30
x = 5.
The answer is 5 in^2
 
        
             
        
        
        
The diameter of the circle is 17.49
 
        
             
        
        
        
Answer:
The reasoning is  a deductive. 
   The reason is because the pattern of  thought is logical, here, scientific methods ( i.e mathematically obtaining and comparing the density of the coin and the  gold ) are used to support the conclusion.
Step-by-step explanation:
Gnerally the reasoning is  a deductive. 
   The reason is because the pattern of  thought is logical and scientific methods (eg mathematical equation (formula for density)) are applied to arrive at the  conclusion.
 
        
             
        
        
        
based on the options given, it looks like -2x+5y would be correct although i am not certain
