In the image two circles are centered at A The circle containing was dilated to produce the circle containing BWhat is the scale factor of the dilation class=

Respuesta :

Answer:

The scale factor of the  dilation is 1/2

Step-by-step explanation:

we have that

The radius of the circle containing B is

[tex]r_1=2\ units[/tex]

The radius of the circle containing B' is

[tex]r_2=1\ units[/tex]

The dilation of circle containing B to circle containing B'  is a reduction

To find out the scale factor divide the radius of circle containing B'  by the radius of the circle containing B

so

[tex]\frac{r_2}{r_1}= \frac{1}{2}[/tex]

Answer: 0.5
