Program to find slant height of cone and pyramid

Given two integers H1 and R representing the height and radius of a cone and two integers H2 and S representing the height and length of base of a pyramid, the task is to find the slant height of the cone and the pyramid.

Examples: 

Input: H1 = 4.5, R = 6, H2 = 4, S = 4.8
Output:
Slant height of cone is: 7.5
Slant height of pyramid is: 4.66476

Input: H1 = 2, R = 4, H2 = 4, S = 8
Output:
Slant height of cone is: 4.47214
Slant height of pyramid is: 5.65685

Approach: The slant height of an object such as a cone or a pyramid is the distance measured from any vertex along a lateral face to the base (along the center of the face). The slant height of a right circular cone is uniform throughout the surface and is given by the formula:

where, 
L is the slant height of the right circular cone
R is the radius of the right circular cone and
H is the height of the right circular cone

The slant height of a pyramid is given by the formula:

where, 
L is the slant height of the pyramid
S is the side of the base of the pyramid
H is the height of the pyramid

Below is the implementation of the above approach:

C++

// C++ program for the above approach
#include <bits/stdc++.h>
using namespace std;

// Function to calculate slant
// height of a cone
void coneSlantHeight(double cone_h,
                     double cone_r)
{
    // Store the slant height of cone
    double slant_height_cone
        = sqrt(pow(cone_h, 2)
               + pow(cone_r, 2));

    // Print the result
    cout << "Slant height of cone is: "
         << slant_height_cone << '\n';
}

// Function to find the slant
// height of a pyramid
void pyramidSlantHeight(double pyramid_h,
                        double pyramid_s)
{

    // Store the slant height of pyramid
    double slant_height_pyramid
        = sqrt(pow(pyramid_s / 2, 2)
               + pow(pyramid_h, 2));

    // Print the result
    cout << "Slant height of pyramid is: "
         << slant_height_pyramid << '\n';
}

// Driver Code
int main()
{
    // Dimensions of Cone
    double H1 = 4.5, R = 6;

    // Function Call for slant height
    // of Cone
    coneSlantHeight(H1, R);

    // Dimensions of Pyramid
    double H2 = 4, S = 4.8;

    // Function to calculate
    // slant height of a pyramid
    pyramidSlantHeight(H2, S);

    return 0;
}
