Write C++ Program to Compute Volume and Surface Area of Sphere

// CPP Program to Compute Volume and Surface Area of Sphere

#include <iostream>
#define PI 3.14

using namespace std;

int main()
{
   float radius = 4;

   double area_sphere;
   // Formula to compute area of sphere
   area_sphere = 4 * PI * (radius * radius);


   double volume;
   // Formula to compute volume of sphere
   volume = (4 * PI * radius * radius * radius)/3;

   cout << "Surface area of Sphere having radius " << radius << " :--> " << area_sphere;
   cout << "\nVolume of Sphere having radius " << radius << " :--> " << volume;


   return 0;
}

Output:

Surface area of Sphere having radius 4.00 :--> 200.96
Volume of Sphere having radius 4.00 :--> 267.95
