Make it better can't read it sorry
        
                    
             
        
        
        
Standard form would be 1.46e-6 because the variable has one degree and the number 6 does not have a degree.
        
             
        
        
        
I belive that the answer should be D) 100 for $10.00 because I had this exact same question one time.
Hope my answer helps!
Thank you for letting me answer!

Step-by-step explanation:
theta = 180 - 123 = 57 degree 
arc length = 2 * pi * R * ( theta / 360)
 = 2 * pi * R * ( 57 / 360)
 = 0.994R cm
