## Lunalovegood 3 years ago How many points are shared by concentric circles? a. 0 b. 1 c. 2 d. infinite points

1. campbell_st

do you know what concentric means..?

2. robert4

Concentric objects share the same center, axis or origin with one inside the other. Concentric do not share any points as long as their radius is different (in which case they are identical, as in share all points).

3. Lunalovegood

so the answer would be d? @robert4

4. robert4

yes i need help @Lunalovegood

5. Lunalovegood

ok :)

6. Lunalovegood

it says thats wrong

7. TuringTest

where does it say that they have the same radius?

8. Lunalovegood

it doesn't

9. TuringTest

that is the peril of taking an answer to a question you don't understand try replying to campbell_st's question

10. Lunalovegood

It mean to have a common center point, or axis

11. TuringTest

ok so draw two (differently sized) concentric circles on a piece of paper. how many places to they cross each other

12. Lunalovegood

0

13. robert4

no why

14. TuringTest

so really there are two answers, depending on whether the two circles have the same radius
