Given:

OA=3 units

OA'=9 units

To find:

The scale factor of the dilation.

Solution:

From the given figure it is clear that the center of dilation is point O. Point A' is the image of point A. So,

$\text{Scale factor}=(OA')/(OA)$

Putting the given values, we get

$\text{Scale factor}=(9)/(3)$

$\text{Scale factor}=3$

Therefore, the scale factor of the dilation is 3.
