**bobpursley**, Tuesday, April 5, 2011 at 8:22pmI am not certain of your comfort with this, however, knowing either the apotherm or the circumradius you can find the other.

circumradius * cos(180/n)=apotherm

so in this case, atotherm=5inches, n=6

so circumradius * cos(30)=5inches

radius= 5inches / .866

Now the area of the circumscribed circle is PI*radius^2

Neat stuff. Thank your teacher.
