Sector area  = 0.5 * r^2 * angle (in radians)
so:
16 pi = 0.5 * r^2 * (90*pi/180)
r^2 = 16 pi /(0.25 pi) = 64 
r = 8 
therefore it would be d 
        
             
        
        
        
Answer:
B. f(x) = 4 log(x+3)
Step-by-step explanation:
B. f(x) = 4 log(x+3) : shifted three units to the left of g(x) = 4 logx
 
        
             
        
        
        
Start by taking away 22.36 from each side so that you are left with 4.73c = 42.57
And then divide each side by 4.73 so you will get c = 9
