What is the sum of a polygon with 30 sides?

What is the sum of a polygon with 30 sides?

A triacontagram is a 30-sided star polygon.

How do you find the area of a polygon with side lengths?

If the number of sides of a polygon is given, the area of the polygon can be calculated with the help of the formula, Area = [(L2 n)/4 tan(180/n)]; where L is the length of its side and ‘n’ is the number of sides of the polygon.

How many sides does a regular polygon have if the interior angle is 30?

As it is a regular polygon, all exterior angles are equal and are 30°. Hence number of sides of the polygon is 360°/30°=12.

What is the sum of the side lengths of a polygon?

The sum of all lengths of the polygon is known as the perimeter. 2. If we multiply the side by two, or double it, then either side of the square will also be doubled. The previous one’s diameter will be the sum of two side lengths of the bigger one.

What is a 200 sided polygon called?

What is the name of a polygon with…?

How do you find the sides of a polygon?

Subtract the interior angle from 180. For example, if the interior angle was 165, subtracting it from 180 would yield 15. Divide 360 by the difference of the angle and 180 degrees. For the example, 360 divided by 15 equals 24, which is the number of sides of the polygon.

How do you find a side of a polygon?

Answer: To find the number of sides of a polygon when given the sum of interior angles, we use the formula: Sum of interior angles = (n – 2) × 180, where n is the number of sides.

What is the sum of interior angle of a polygon?

To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal.

What is the sum of the measures of the interior angles of a regular polygon if each exterior angle measures 72?

Let the number of sides of the polygon be \[n\]. It is given that the measure of each exterior angle of the polygon is \[72^\circ \]. $\therefore $ The number of sides of a polygon with each exterior angle \[72^\circ \] is 5. In all cases, the sum of exterior angles of a regular polygon is taken to be \[360^\circ \].

How do you find the sum of a polygon?

To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides.

What is a 29 sided polygon called?

What is the name of a polygon with…?

How do you find the area of a regular polygon?

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides Apothem = a segment that joins the polygon’s center to the midpoint of any side that is perpendicular to that side

How to calculate the length of a polygon?

Enter any 1 variable plus the number of sides or the polygon name. Calculates side length, inradius (apothem), circumradius, area and perimeter. Calculate from an regular 3-gon up to a regular 1000-gon. Units: Note that units of length are shown for convenience. They do not affect the calculations.

When is the number of sides of a polygon equal to 3?

When the number of sides, n, is equal to 3 it is an equilateral triangle and when n = 4 is is a square. The following formulas were used to develop calculations for this calculator where a = side length, r = inradius (apothem), R = circumradius, A = area, P = perimeter, x = interior angle, y = exterior angle and n = number of sides.

How to calculate the perimeter of a polygon?

If the figure is a polygon such as a triangle, square, rectangle, pentagon, etc., then the perimeter is the sum of the edge lengths of the polygon. For example, a square with side length 3 has perimeter 3+3+3+3 = 12. 3+3+3 +3 = 12. Any closed figure has a perimeter, such as the irregular polygon to the right with perimeter
