Circle from stars

[anubiskt]

Hello,
can you help me solve one mathematical problem? It is:

Some stars can make circle (on picture). How many stars with 45 corners do we need to create the longest possible circle?

Thank you a lot.

Hi,
Yes we can help. Can you please tell where you are stuck? Can we see some of your work to see if you made any mistakes?
Can you explain what you mean by the longest possible circle?
