WRITE A C PROGRAM TO CALCULATE THE AREA OF CIRCLE AND MODIFY THE SAME PROGRAM TO FIND THE VOLUME OF CYLINDER GIVEN IT'S HEIGHT AND RADIUS.

  #include <stdio.h>

int main()

{

    int radius;

    float pie=3.14,area;

    printf("what is the radius of the circle \n");

    scanf("%d",&radius);

    area=pie*radius*radius;

    printf("the area of circle is %f\n",area);

    float height=7,volume;

    volume = pie*radius*radius*height;

    printf("the volume of cylinder is %f",volume);

    

    return 0;

}
