Suppose x is any positive number. Circle 1 has a center at (-2,-3) and a radius of 4x. Circle 2 has a center of (0,-4) and a radius of 5x.

Why is circle 1 similar to circle 2?

- Circle 1 is a translation of 2 units left and 1 unit up from circle 2 and has a dilation of circle 2 with a scale factor of 1.5

- Circle 1 and circle 2 have the same area, and circle 1 is a dilation of circle 2 with a factor of 0.8

- Circle 1 and circle 2 have the same circumference, and circle 1 is a dilation of circle 2 with a scale factor of 1.25

OR

-Circle 1 is a translation of 2 units left and 1 unit up from circle 2 and a dilation of circle 2 with a scale factor of 0.8
