Computer Science » C Program » Circumference of Circle
Definition :
1. Ellipse in which the two axes are of equal length.
2. Plane curve generated by one point moving at a constant distance from a fixed point.
3. You can compute the circumference of a circle if you know its radius.
Image :
Formula :
circumference (C) = 2πr
Where,
C is the circumference of the circle
r is the radius of the circle
Program :
#include<stdio.h>
int main()
{
int radius;
float circumference;
printf("nEnter the radius of Circle : ");
scanf("%d", &radius);
circumference = 2 * 3.14 * radius;
printf("ncircumference of Circle : %f", circumference);
return (0);
}Output :
Enter the radius of Circle : 2.0 circumference of Circle : 12.56
