3. consider this dilation. (a) is the image of the dilation a reduction or an enlargement of the original figure? explain.
(b) what is the scale factor? explain.

Reduction, 1/2

Step-by-step explanation:

We can already see that the prime figure is smaller, so we can justify that it is a reduction.

We can look at the points of the original figure and if we divide them by 2, we get the prime figure coordinates so we can conclude that the scale factor is 1/2.

i pretty sure it is

other answer is correct. i had used the radius of the radius somehow. a website:
