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.
That means each of the other angles in the triangle are 70 deg. Since the corner of the nonagon is the sum of the angles of the two triangles that make up the corner, the interior angle of a nonagon is 140 deg. Therefore the exterior angle of a nonagon is (180 - 140) = 40 deg. Each interior angle of a regular nonagon is 140 degrees.
