1 Fill the cupcake liners 2/3 to 3/4 of the way full (about 3 tablespoons). Avoid adding too much batter or the cupcakes will overflow from the cups as they bake and cause a mess.  There are several ways to fill your paper cupcake liners with cupcake batter:
In geometry, any polygon with ten sides and ten angles and ten vertices is called as Decagon. The sum of angles in a decagon is 1440Â°. In real life, Decagon shape can be seen in few coins, tiles and mugs. 2 Peso Coin of the Republic of the Philippines has a decagon shape. The number of diagonals in a polygon is given by the formula n(nâ3)2.
The sum of the interior angles of an octagon is 1080 degrees.   In a regular octagon, divide by 8 for each angle = 135Â°.   The formula for this is Sum = 180 (n-2) wheâ¦re n is the  number of sides.   (or 180n - 360)    You can take the polygon and make [N] triangles, with points  touching at the 'center'.
