In this case, we'll have to carry out several steps to find the solution.
Step 01:
data:
diagram
Step 02:
scale factor:
We must analyze the polygons to find the solution.
1. Circle A ===> Circle B
Circle A:
ra = 5
Circle B:
rb = 3
scale factor (k):
ra * k = rb
5 * k = 3
k = 3 / 5
k = 0.6
The answer is:
scale factor of dilation = 0.6
