Circle A has center of (−2, 4) and a radius of 4, and circle B has a center of (3, 9) and a radius of 8. What steps will help show that circle A is similar to circle B?

Translation, 5 units to the right and 5 units up followed by  Dilation of scale factor 2

Step-by-step explanation:

The equation of any circle is (x - h)² + (y - k)² = r², where h and k are

Circle A has a center of (-2,4) and a radius of 4

∵ (h , k) is the center of the circle and r is its radius

∴ h = -2 and k = 4

∵ r = 4

∴ r² = 4² = 16

 Circle A is dilated by a scale factor of 2

Hope this helps.

the radius is 2 times the diameter.

step-by-step explanation:

i believe it's a.

i'm not sure on this one, most likely correct.
