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();
}
