Answer:

The scale factor of the dilation is 1/2

Explanation:

we have that

The radius of the circle containing B is

$r_1=2\ units$

The radius of the circle containing B' is

$r_2=1\ units$

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

(r_2)/(r_1)= (1)/(2)
