A. Dilate Circle A about A by a scale factor of 2 followed by a translation of 8 left and 2 up.

B. Translate Circle A 8 left and 2 up.

C. Dilate Circle B about B by a scale factor of 1/2 followed by a translation of 8 left and 2 up.

D. Dilate Circle B about B by a scale factor of 1/2 followed by a translation of 8 right and 2 down.

Answer 1

do you see that this radius of 8 cm and this diameter of 16 cm so mean the same ? - hope you understand me

Answer 2

B
