# How to find the length of the apothem?

As long as the length of the sides is known, the apothem can be determined by using the formula: apothem= s/2 tan (180/n). In this formula, “s” is the length of the sides and “n” is the number of sides.

## Moreover, how do you find the Apothem of a regular polygon?

We can also use the area formula to find the apothem if we know both the area and perimeter of a polygon. This is because we can solve for a in the formula, A = (1/2)aP, by multiplying both sides by 2 and dividing by P to get 2A / P = a. Here, the apothem has a length of 4.817 units.## In addition, you may be interested in how do you find the length of an Apothem of a hexagon?

To do this, use a calculator or a trigonometry table. Multiply the tangent by 2, then divide the side length by this number. This will give you the length of the apothem of your hexagon. So, the apothem of a regular hexagon with 8-cm sides is about 6.93 cm.## Accordingly, the question is what is a 15 sided shape called?

In geometry, a pentadecagon or pentakaidecagon or 15-gon is a fifteen-sided polygon.## Do you have your own answer or clarification?
