First he found the side length of a regular heptagon inscribed in a circle of radius 12 cm. You can modify this to find the side length of a regular hexagon inscribed in a circle of radius 4 cm. Then he developed an expression for the area of a regular polygon with side length a and n sides. I hope this helps,
