Circumference :-Circumference of circle is the distance around the circle. Calculate The Circumference of Circle By Given Formula
Circumference = 2*π*r
Here PI (π) is a Greek Letter and r is a Radius (1/2 Of Diameter )
PI (π) = 3.141592653589793 Approx. It Is A Constant Value for more about Circumference Click Here
Area =π *r*r

int rad;
float PI = 3.14, area, ci;
printf("\nEnter radius of circle: ");
scanf("%d", &rad);
area = PI * rad * rad;
printf("\nArea of circle : %f ", area);
ci = 2 * PI * rad;
printf("\nCircumference : %f ", ci);
return (0);
}
