Question

Circle A has center of (4, 5), and a radius of 3 and circle B has a center of (1, 7), and a radius of 9. What steps will help show that circle A is similar to circle B? (6 points) a Translate circle A using the rule (x + 3, y − 2). b Dilate circle A by a scale factor of 3. c Rotate circle A 90° about the center. d Reflect circle A over the x-axis.

Answer 1

Answer:

Steps a and b

Step-by-step explanation:

The first circle has radius 3 and the second one has radius 9. Note that the step a moves the center of the first circle to the center of the second circle. That is it translates the point(4,5) to the point (1,7) if we use the rule (x-3, y+2). once the centers are the same, by dilating the circle A by  a factor of 3 gives us the same radius.
