Question

Write a C++ program to find the area of a shape whose area is given by the formula Area = 2+4r + πr^6

Answer 1

//importing the library
#include <iostream>
#include <math.h>
using namespace std;
 
int main() { 
 
 float r,Area=0; //initilization of the variable 
 
 cout<<"Enter the value of r : "<<endl;//taking input from the user 
 cin>>r;
 
  Area = 2+4*r + 3.14*pow(r, 6); // calculating the area of the shape 
  
  cout<<"Area of the shape :"<<Area; //here you will get output of the program 
return 0;
}
//end of the program

OUTPUT SCREEN IS :

value of r: 5

so,

Area : 49084.5
