Question

For #1 - 4, use the given diagrams and what you have learned about similar polygons. Hint: use the radius of the circles.

Answer 1

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
