Circle A has center of (5, -2) and a radius of 7, and circle B has a center of (7, -8) and a radius of 35. What steps will help show that circle A is similar to circle B? (5 points)
Select one:
a. Rotate circle A 90° counterclockwise about the center.
b. Translate circle A using the rule (x-2, y+6).
c. Reflect circle A over the y-axis.
d. Dilate circle A by a scale factor of 5.

Well, can you tell me when are the 2 circles said to be similar?

anonymous · Answer

im not sure thats why i posted it

mathslover · Answer

Okay, no problem. See, two circles can be made similar by finding the difference in the centre coordinates .

mathslover · Answer

Here, we have coordinates of centre of 

Circle A = (5,-2) 

Circle B = (7,-8)

So, we will find the diff. in the above coordinates . Can you find the difference?
