Circle A has center of (0, 4) and a radius of 6, and circle B has a center of (-3, 5) and a radius of 24. What steps will help show that circle A is similar to circle B?

Translate circle A using the rule (x+3, y−1).

Rotate circle A 180° about the center.

Dilate circle A by a scale factor of 4. <--?

Reflect circle A over the line y=x.
