find the surface area of a regular polygon circumscribed around a pyramid in php

To find the surface area of a regular polygon circumscribed around a pyramid, you can use the formula:

Surface Area = (Perimeter of the base x Slant Height of the pyramid) / 2

To find the perimeter of the regular polygon, you can use the formula:

Perimeter = number of sides x length of each side

Here's the PHP code to calculate the surface area of a regular polygon circumscribed around a pyramid:

main.php
<?php
// Function to calculate surface area of a regular polygon circumscribed around a pyramid
function surfaceArea($sides, $length, $height) {
    $perimeter = $sides * $length;
    $slant_height = sqrt(pow($height, 2) + pow($length / 2, 2));
    $surface_area = ($perimeter * $slant_height) / 2;
    return round($surface_area, 2); // Round off to 2 decimal places
}

// Example usage
$sides = 4; // Number of sides of the polygon
$length = 10; // Length of each side
$height = 8; // Height of the pyramid
echo "Surface Area: " . surfaceArea($sides, $length, $height) . " sq units";
?>

In this example, the function surfaceArea() takes three parameters sides, length, and height and returns the surface area of the regular polygon circumscribed around a pyramid.

You can call this function with your desired values of sides, length, and height to calculate the surface area of any regular polygon circumscribed around a pyramid.
