Answer:

Option (2) 1.5

Step-by-step explanation:

Rule for the dilation of an image by a scale factor is,

Scale factor = \frac{\text{Radius of image circle A'}}{\text{Radius of pre-image A}}=\frac{r'}{r}

                    = \frac{(2\pi) r'}{(2\pi) r}

                    = \frac{\text{Circumference of image}}{\text{Circumference of pre-image}}

                    = \frac{10.5}{7}

                    = 1.5

Therefore, scale factor was used to create a circle A' = 1.5

Option (2) will be the correct option.
