Why is circle 1 similar to circle 2?

Circle 1: center (−1, 10) and radius 4.8

Circle 2: center (−1, 10) and radius 1.2

Circle 1 is congruent to circle 2.
Circle 1 and circle 2 have the same center.
Circle 2 is a dilation of circle 1 with a scale factor of 3.6.
Circle 1 is a dilation of circle 2 with a scale factor of 4.

well the idea that all circles are similar is true. the circles have the same center so if you dilate circle 2 by the scale factor of by a scale factor of 4 they will be the same so looks to me like the answer is D)circle 1 is a dialation of circle 2 with a scale factor of 4

Circle 1 is a dilation of circle 2 with a scale factor of 4.

Dilation of figures

Dilation is a way of changing the size of an image using a scale factor.

Given the following parameters

Circle 1: center (−1, 10) and radius 4.8

Circle 2: center (−1, 10) and radius 1.2

The dilation can be determined by taking the radius of the circles.

Scale factor = 4.8/1.2

Scale factor =4

Hence we can conclude that Circle 1 is a dilation of circle 2 with a scale factor of 4.
