Circle a with center at (3, 4) and radius 2 is similar to circle b with center at (โˆ’4, โˆ’5) and radius 3. below is an incorrect informal argument for proving two circles are similar: step 1 translate circle b to the right 9 units and up 7 units to form concentric circles. step 2 dilate circle b to be congruent to circle a using scale factor of k = r sub two over r sub one equals two over three step 3 when an object is dilated, the dilated object is similar to the pre-image, thus the two circles are similar. what is the first incorrect step, and how can it be fixed? a. all steps are correct b. step 1, translate circle b to the right 7 units and up 9 units c. step 2, use scale factor of k = r sub two over r sub one equals three over two d. step 3, replace dilated with translated
