Question

Is this answer correct? *Study Island**

Answer 1

Just checking to be sure, all circles are similar right?

Answer 2

These wouldn't be congruent because the radius doesn't fit the other circle's diameter. Not congruent, but still similar?

Answer 3

Yes, the radius of the first would be 6, compared to the others 8. They are not congruent, but are similar

Answer 4

yes. every circle in the world is "similar" to every other circle

Answer 5
