This tutorial will discuss how to write swift program to calculate area of enneagon. A enneagon is a polygon with 9 straight sides and 9 vertices. The sum of all the interior angles is 1260 degree. The total amount of space enclosed inside the nine sides of the enneagon is known as the area of the enneagon. Formula Following is the formula of the area of the enneagon − Area = ((x2*9) / 4*tan (20°)) ∼= (6.18 * x2) Here, x is the side of the enneagon. Below is a demonstration of the same − Input Suppose our ... Read More

Each angle of equilateral triangle is 60 degrees. It is also known as 3-side polygon. Area of Equilateral Triangle The amount of space occupied between the three lines of the triangle is known as the area of the equilateral triangle. Formula Following is the formula − Area = √3x2/ 4 Here x is the side of the equilateral triangle. Below is a demonstration of the ... Read More
This tutorial will discuss how to write swift program to find the mid-point of a line. A point lies between the middle of two points is known as mid-point. Suppose we have two points A and B and C point is the mid-point located between A and B. Midpoint always divide lines segment in equal parts. Or we can say mid-point is always equidistant from other two points. Formula Following is the formula − Midpoint = ((a1+a2)/2, (b1+b2)/2) Below is a demonstration of the same − Input Suppose our given input is − Point 1: (5.0, 6.0) ... Read More
This tutorial will discuss how to write swift program to calculate distance between two points. Suppose we have two points and a line connect these points together. So the length of the line is known as the distance between two points in a plane. This formula is used to find the distance between two points in XYplane. Formula Following is the formula − Distance = sqrt((a2-a1) + (b2-b1)) Below is a demonstration of the same − Input Suppose our given input is − Point 1: (1.0, 2.0) Point 2: (3.0, 4.0) Output The desired output would ...

This tutorial will discuss how to write swift program to calculate area of pentagon. A pentagon is a two-dimensional shape with 5 sides. It also contains five interior angles and their sum is 540 degrees. It is also known as five side polygon. The total amount of space enclosed inside the five sides of the pentagon is known as the area of the pentagon. Formula Following is the formula of the area of the pentagon: Area = 1/4(sqrt(5(5+2√5))q2) Below is a demonstration of the same − Input Suppose our given input is − side = 6 ... Read More
This tutorial will discuss how to write swift program to calculate area of hexagon. A hexagon is a two-dimensional shape with 6 sides of same or different length. It contains six vertices and six interior angles. Hexagon is classified into four types according to their length and internal angles − Regular Hexagon Irregular Hexagon Convex Hexagon Concave Hexagon In this article we will find the area of Regular hexagon. Regular hexagon are those hexagons in which the all the sides are of equal length. The sum of all six interior angles is 720 degrees and the sum of ... Read More
This tutorial will discuss how to write swift program to calculate area of octagon. An octagon is a two-dimensional shape with 8 sides and also consists of eight interior and exterior angles. The total amount of space enclosed inside the octagon is known as the area of the octagon. Formula: Following is the formula of the area of the octagon − Area = 2 *(side)2*(1+√2) Below is a demonstration of the same − Input Suppose our given input is − side = 15 Output The desired output would be − Area of octagon = 1086.3961030678927 ...

This tutorial will discuss how to write swift program to calculate area of circle inscribed in square. We have a figure in which a circle is inscribed in a square. Which means the centre of the circle and the square is same and the diameter of the circle is equal to the length of the side of the square. If we have at least one measurement of square or the circle, then we can easily calculate the area and perimeter of the square, or area and circumference and area of the circle. Here we find the area of the ... Read More
This tutorial will discuss how to write swift program to print Diagonal Matrix pattern. Diagonal matrix are those matrix in which all the elements are 0 except the principal diagonal.Or we can say that in a diagonal matrix off diagonal blocks are 0 and main diagonal blocks are square matrices. To create a diagonal matrix pattern we can use any of the following method − Using nested for loop Using stride Function Below is a demonstration of the same − Input Suppose our given input is − Num = 3 Output The desired output would be − 1 0 ...
