Problem: Write a C++ program to find the volume and surface area of a solid cone by taking values of radius and height of the cone from user. [Define required constant values]

Code: 

#include <iostream>
#include <cmath>
#define pi 3.14159

using namespace std;

int main(){
    float r, h, l, vol, sa;

    cout << "Enter the radius of the cone: ";
    cin >> r;


    cout << "Enter the height of the cone: ";
    cin >> h;

    l = sqrt(pow(r,2)+pow(h,2)); //slant height

    vol = (pi*r*r*h)/3;

    sa = (pi*r*l)+(pi*r*r);

    cout << "The Volume is " << vol << " and The Surface area is "<<sa;


}

Output: 

Enter the radius of the cone: 2
Enter the height of the cone: 7
The Volume is 29.3215 and The Surface area is 58.3086
Process returned 0 (0x0)   execution time : 3.997 s
Press any key to continue.
