Answer:

  a.  5/2

  b.  not a dilation

  c.  not a dilation

Step-by-step explanation:

You want the scale factor of the dilation from the smaller figure to the larger one.

a. Circle

Any circle is a dilation of any other circle. The dilation factor is the ratio of the radii: 5/2.

b. I

The aspect ratio of the smaller figure is 4:1. For the larger figure, it is 3:1. The larger figure is not a dilation of the smaller one.

c. T

The aspect ratio of the smaller figure is 7:5. For the larger figure, it is 7:4. The larger figure is not a dilation of the smaller one.

Additional comment

Here, we've taken the aspect ratio to be the ratio of the vertical dimension to the horizontal dimension: 3.5/2.5 = 7/5, for example.
