We can find the apothem from the side length and the number of sides. |
I have mentioned the above to show how very nearly these ratios agree with my exact ratio of 21 to 34 half base to apothem. |
Given a circle, the apothem is the perpendicular distance from the midpoint of a chord to the circle's center. |
In the Pyramid Cheops, altitude is very nearly a mean proportional between apothem and half base. |
In a regular polygon, we have an apothem, a number and a length of sides which do not belong to the base class shape. |
Once the perimeter and the apothem are known, the formula relating the two to area can be used to solve for the area. |
