The scale factor of the dilation is 3. The correct option is C.
What is the scale factor?
The scale factor is defined as the proportion of the new image's size to that of the previous image. decision-making. Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.
From the given image:-
The initial size in the image is calculated as 11 - 2 = 9
The dilated size in the image is calculated as 5 - 2 = 3
The scale factor will be given as:-
Scale factor = ratio of the initial size to the dilated size
Scale factor = Initial size / Dilated size
Scale factor = 9 / 3 = 3
Therefore, the scale factor of the dilation is 3. The correct option is C.
