Answer:
50% is the increase
Step-by-step explanation:
Check the picture below.
Dilate circle A by a scale factor of 4.
Dilating circle A by 4 would be the same as multiplying its radius of 6 by 4, which would make it 24.
The radius of circle B is 24.
Rotating it wouldn't change anything (it's a circle), and I don't think reflecting and translating show circle similarity
