Question

Circle A has center of (2,3) and a radius of five, and circle B has a center of (1,4) and a radius of 10.

What steps will help show that Circle A is similar to Circle B?

A.) Dilate circle A by a scale factor of 2

B.) Translate circle A using the rule. (x + 1, y - 1).

C.) Rotate circie A 180° about the center.

D.) Reflect circle A over the y-axis.

Answer 1

Answer:

• A) Dilate circle A by a scale factor of 2

Step-by-step explanation:

For two triangles to be similar, they need to have the same radius.

• Circle A has a radius of 5, and Circle B has a radius of 10.

So, to make them similar, we can simply :

• dilate circle A by a scale factor of 2

This would give Circle A and B the same radius, and they will be similar.
