The two circles shown are similar. Find the scale factor of the smaller circle to the larger circle.

3 to 2

2 to 3

5 to 3

3 to 5

Option D:

Scale factor of the smaller circle to the larger circle = 3 : 5

Solution:

Given the two circles are similar.

Radius of the smaller circle = 3

Radius of the larger circle = 3 + 2 = 5

Let us find the scale factor for the two similar circles.

Scale factor of the smaller circle to the larger circle = 3 : 5

Option D is the correct answer.

Hence scale factor of the smaller circle to the larger circle = 3 : 5
