PLEASE HELP
What is the ratio between the radii of circles A and B and what does that ratio represent in terms of nonrigid transformations.

Answer 1

Answer:

The ratio between the radii of circles A and B is equal to $\frac{4}{3}$ and this ratio represent the scale factor

Step-by-step explanation:

Let

x -----> the radius of circle A

y -----> the radius of circle B

z -----> the ratio between the radii of circles A and B

so

$z=\frac{x}{y}$

we know that

$x=4\ units$ ----> radius of circle A

$y=3\ units$ ----> radius of circle B

Find the ratio z

$z=\frac{4}{3}$

The ratio represent the scale factor of the dilation of radius of circle B to obtain the radius of circle A

Circles A and B are similar, because A translation, followed by a dilation will map one circle onto the other
