Question

circle n is a dilation of circle m with point r as the center of dilation. circle u is a dilation of circle t with point r as the center of dilation. find the scale factors. what is the scale factor that takes circle m to circle n? solve on paper if you need to. then, enter your answer on zearn. the scale factor from circle m to circle n is \boxed{}.

Explanation:

Step1: Identify radii of circles

Let radius of circle $m$ be $r_m$, radius of circle $n$ be $r_n$. From the grid, $r_m = 3$ units, $r_n = 6$ units.

Step2: Calculate scale factor

Scale factor = $\frac{\text{Image radius}}{\text{Pre-image radius}}$
$\text{Scale factor} = \frac{r_n}{r_m} = \frac{6}{3}$
