2. Circumference = 2 * 3.14 * radius

Answer 1

Answer:

#include<stdio.h>

void main()

{

int r,Area,Circumference;

printf (" Please enter the radius of the circle\n");

scanf ("%d",&r);

Area=3.14*r*r;

Circummference=2*3.14*r;

printf("The Area of the circle is given by %d sq.metre and the circumference    is given by %d metres\n",&Area,&Circumference);

}
