Problem 46 of 7
Describe a translation plus dilation mapping circle center (5,-2), radius 4 to circle center (5,-2), radius 12.
Using a hint is okay. It just tells the trainer to give you a little more review.

align centers then scale radius.
Hidden until you reveal it.
Circles may have different centers and radii; transformation must align centers and scale radius.

Full solution stays hidden until you ask for it.
1. Translate the original center to the target center.
2. Compare radii to find the scale factor.
3. Apply dilation about the aligned center.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Dilation alone when centers differ.
