Write a program to find the number of bytes occupied by various data types using the sizeof operator

Write a program in C++, which takes the radius from the user and calculates the area of the sphere i.e Area=4pr2

 

(Hint  p = 3.1416

 

Area = 4 * 3.1416 * r * r)

Write a program in C++, which takes the radius from the user and calculates the area of the sphere i.e Area=4pr2  

SOLUTION :

#include<iostream>

using namespace std;

int main ()

{

   int radius,area;

   cout<<"Enter the Radius :";

   cin>>radius;

   area=4 * 3.1416 * radius * radius;

    cout<<"Area :"<<area<<endl;

    return 0;

}
