Answer 1

Explanation:

The central angle for circles A and B can be calculated as the ratio of arc length to the radius.

For circle A, the arc length is 4π and the radius is 12, so the ratio is

4π/12 = 1/3 π

In the same way, for circle B, the arc length is π and the radius is 3, so the ratio is

π/3 = 1/3 π

Therefore, both angles have the same measure and Lin is correct, they are congruent. So, the answer is

Answer:

Lin is Correct because the ratio of arc length to radius for circle A is 1/3 pi and the ratio of arc length to the radius in circle B is 1/3 pi
