Write C++ program to finds the area of the circle and the volume of the sphere with given radius.

#include <iostream.h> 
 #include<conio.h> 
 const float pi = 3.1415; 
 void main() 
 { 
       float area, volume, r, radius; 
       clrscr(); 
       cout<<"Enter Radius "; 
       cin>>r; 
       radius = r * r; 
       area = pi * radius; 
       volume = pi * radius * r; 
       cout<<"Area of the Circle "<<area<<endl; 
       cout<<"Volume of the Sphere "<<volume<<endl; 
       getch(); 
 }
