Answer:
B
r=9.7
C=60.95
Step-by-step explanation:
Given diameter of 19.4
r = d/2
19.4/2
r=9.7
C= 2(pi)r
2(pi)(9.7)
60.95 = C

General Idea:
W
hen we are given a point P(x, y) centered at origin with a scale factor of k, then the dilated point will be given by P' (kx, ky)
When , then P' is enlargement of P
, then P' is enlargement of P
When  , then P' is reduction of P
, then P' is reduction of P
Applying the concept:
In the diagram given A'B'C' is enlargement of ABC. So the correct option will be option A.  , enlargement
, enlargement
 
        
             
        
        
        
X + 100 = 4x +49 
x= 17
158+148+32+x = 360
338+x= 360
x= 22
