Write a C program to read radius and Calculates the volume and circumference of a circle


#include
int main()
{
 int radius;
 float pi=3.1416,volume_of_a_circle;
 float circumference_of_a_circle;
 printf("Enter a radius ");
 scanf("%d",&radius);
 volume_of_a_circle= pi*radius*radius;
 printf("volume of a circle is %.2f \n",volume_of_a_circle);
 circumference_of_a_circle=2*pi*radius;
 printf("circumference of a circle %.2f ",circumference_of_a_circle);
 getch();
}
