Write a program in C++ to calculate the volume of a sphere

Solution:

#include <iostream>
using namespace std;
int main()
{
int rad1;
float volsp;
cout << "\n\n Calculate the volume of a
sphere :\n";
cout << "
---------------------------\n";
cout<<" Input the radius of a sphere : ";
cin>>rad1;
volsp=(4*3.14*rad1*rad1*rad1)/3;
cout<<" The volume of a sphere is : "<<
volsp << endl;
cout << endl;
return 0;
}
