The scale factor for a model is 5 cm = 16.05 cm.

Step-by-step explanation:

Given:

Model: 9.5cm Actual : 30.5m and the scale factor for model is 5 cm.

Now, we need to find the actual shape for the scale factor 5 cm.

Let the actual shape be .

Now, for getting the actual shape we set for proportion:

5:x :: 9.5:30.5

5:x = 9.5:30.5

Then, convert it into fractions:

Now, on cross multiplying we get:

Dividing both sides by 9.5 we get:

Therefore, the scale factor for a model is 5 cm = 16.05 cm.
