Answer:
#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.
