Draw a circle circumscribing a regular hexagon with side 5 cm.
Steps of Construction:
i) Draw a regular hexagon ABCDEF with each side equal to 5 cm and each interior angle 120º.
ii) Join its diagonals AD, BE and CF intersecting each other at O.
iii) With centre as O and radius OA, draw a circle which will pass through the vertices A, B, C, D, E and F.
This is the required circumcircle.
