I believe it should be 1.4 since the answer you get is 1.4112903226... you would round but on the tenths place 1.4
        
                    
             
        
        
        
Answer:
C
Step-by-step explanation:
Use πr²
 
        
                    
             
        
        
        
217x+99=25
217x=25-99
217x= -74
X=-74/217
 
        
             
        
        
        
Standardized z score for the act result  =  (30 - 21.5) / 5.4  = 1.574
so for the sat ressult we have 1.574 = (X - 1498) / 316
X  = 316 * 1.574 + 1498  =  1995  answer
