Radius of a polygon formula
WebJan 30, 2024 · For example, if you connect the centers of the perimeter pixels (as suggested in the paper) then using the length of those diagonal lines to measure the perimeter as a polygon, now you will get a better measure of the perimeter. As such, your nice little formula will now be a better measure of the circularity of the object. 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.
