Why is circle 1 similar to circle 2?

circle 1: center (−1, 10) and radius 4.8

circle 2: center (−1, 10) and radius 1.2

a-circle 1 is a dilation of circle 2 with a scale factor of 4.

b-circle 1 and circle 2 have the same center.

c-circle 2 is a dilation of circle 1 with a scale factor of 3.6.

d-circle 1 is congruent to circle 2.
