*Rules 1:see formula.


Question 1
Find the area of circle:
area=3.14* radius*radius

Answer
Start>>read radius>>area=3.14*radius*radius>>display output>>end

#include<iostream.h>//header
main()//start body
{//open curly bracket
 //declare variable
   float area;
   float radius;
 //input 1
   cout<<"enter radius";
   cin>>radius;
 //formula
   area=3.14*radius*radius
 //output
   cout<<"answer="<<area;
 return 0;
}//close curly bracket
 //end body
  


Question 2
Multiply and divide two FLOAT number, num 1 and num 2 with using the formula below:-

multiply=num 1*number 2
divide=num 2/num 1

Answer
Start>>read num 1,num 2>>multiply=num 1*num 2,divide=num 2/num 1>>display output>>end

#include<iostream.h>//header
main()start body
{//open curly bracket
 //declare variable
   float num 1;
   float num 2
   float multiply;
   float divide;
 //input 1
   cout<<"num 1";
   cin>>num 1;
 //input 2
   cout<<"num 2";
   cin>>num 2;
 //formula
   multiply=num 1*num 2;
 //output
   cout<<"multiply="<<multiply;
 //formula
   divide=num 2/num 1;
 //output
   cout<<"divide="<<divide;
 return 0;
}//close curly bracket
 //end body
