    If you inscribe 4 circles inside a bigger circle and then add another smaller circle, touching the other 4 circles, what is the radius of the smallest circle (in the centre) if the radius of the biggest circle is 10cm?

  3. Is the radius of the four circles the same?

    Assuming four circles are identical, that's everything you may need. Think how these are related to the radii of circles in question.
