Ac++ program to determine the area and circumference of a circle

#include<iostream.h>

#include<conio.h>

void main()

{

clrscr();

float radius, area_circle, circum_cirlce;

cout<<""Enter the radius of the circle :"";

cin>>radius;

area=3.14*radius*radius;

circum=2*3.14*radius;

cout<<""Area of the circle = ""<<area_circle<<""\nCircumference of the circle = ""<<circum_circle<<""\n"";

getch();

}

Explanation:

Here the program needs to find area and circumference of the circle. For that we need radius.

So 3 variables are declared, where radius to capture radius, area_circle to apply the formula and obtain the value for area of circle and in similar way for circumference we sue the variable circum_circle and finally we print the result.
