WebThe apothem formula , when the radius is given is: a a = r.cos180 n r. c o s 180 n Where r r = radius. n n = number of sides Cos C o s = cosine function which is calculated in degrees. … WebThe area of a regular polygon is one-half the product of its apothem and its perimeter. Often the formula is written like this: Area=1/2 (ap), where a denotes the length of an apothem, and p denotes the perimeter. When an n-sided polygon is split up into n triangles, its area is equal to the sum of the areas of the triangles. WebJan 11, 2024 · You can use this generic formula to find the sum of the interior angles for an n -sided polygon (regular or irregular): Sum of interior angles = (n-2)\times 180° (n − 2) × 180° Sum of interior angles = 10\times 180°=1800° 10 × 180° = 1800° Once you know the sum, you can divide that by 12 to get the measure of each interior angle: dynamatic hls
