wikiHow Hexagon Apothem Calculator To find the apothem of a regular hexagon (a hexagon with all sides and angles equal), you can use the following formula: Apothem = (Side Length) × √3 / 2 Here's how you can calculate the apothem: Determine the side length of the hexagon. Let's assume it is represented by "s". Apply the formula: Apothem = s × √3 / 2 For example, let's say the side length of the hexagon is 6 units. Using the formula: Apothem = 6 × √3 / 2 To simplify, the square root of 3 is approximately 1.732. Substituting this value: Apothem = 6 × 1.732 / 2 Apothem ≈ 10.392 Therefore, the apothem of the hexagon with a side length of 6 units is approximately 10.392 units. Page
