To determine the **scale factor** from circle **g** to circle **h**, we need to understand the relationship between corresponding points on the two circles after dilation with respect to point **R** (the center of dilation). 

Let’s break this down step by step:

1. **Definition of Scale Factor**:  
   The scale factor of a dilation is the ratio of the distances from the center of dilation (point **R**) to a point on the image (circle **h**) and the corresponding point on the pre-image (circle **g**). In other words:

   \[
   \text{Scale Factor} = \frac{\text{Distance from R to point on circle h}}{\text{Distance from R to corresponding point on circle g}}
   \]

2. **Corresponding Points**:  
   The points **A, B, C, D** are on circle **g**, and each has a corresponding point on circle **h**. For each pair of points on circle **g** and circle **h**, the scale factor will be the same if the dilation is consistent.

### What is Required:

- To find the **scale factor**, we need the distance from point **R** to each point on circle **g** (i.e., distance from **R** to **A**, **B**, **C**, and **D**) and the distance from point **R** to the corresponding points on circle **h**.
- If the dilation is uniform (same for all points), the ratio of the distances from **R** to any pair of corresponding points on circles **g** and **h** will give us the **scale factor**.

### Answer Structure:

| **Distance from R** | **Point on circle g** | **Corresponding point on circle h** | **Scale factor** |
|---------------------|-----------------------|------------------------------------|-----------------|
| ?                   | A                     | A'                                 | \( k = \frac{\text{Distance from R to A'}}{\text{Distance from R to A}} \) |
| ?                   | B                     | B'                                 | \( k = \frac{\text{Distance from R to B'}}{\text{Distance from R to B}} \) |
| ?                   | C                     | C'                                 | \( k = \frac{\text{Distance from R to C'}}{\text{Distance from R to C}} \) |
| ?                   | D                     | D'                                 | \( k = \frac{\text{Distance from R to D'}}{\text{Distance from R to D}} \) |

To calculate the **scale factor** for each point, you need to know the distances from **R** to points **A**, **B**, **C**, and **D** on circle **g** and from **R** to the corresponding points on circle **h**.

### Clarification Needed:
- Do you have the specific distances from **R** to these points?
- If so, I can plug those into the table and calculate the scale factor.
