To find the scale factor between circle A and circle B, we can use the formula for the scale factor, which is the ratio of the radii of the two circles.
The radius of circle A is 14 feet, and the radius of circle B is 172 feet.
The scale factor from circle A to circle B is calculated as follows:
\[ \text{Scale Factor} = \frac{\text{Radius of Circle B}}{\text{Radius of Circle A}} = \frac{172}{14} \]
Now, calculate this fraction:
\[ \frac{172}{14} \approx 12.2857 \]
Rounding to the nearest whole number gives us approximately 12.
Thus, the scale factor from circle A to circle B is 12:1.
The correct response is:
12:1
