Program:

#include"stdio.h"
int main()
{
	float r, area, perimeter;
	float compute(float,float*);
	printf("\n enter the radius of the circle:");
	scanf("%f",&r);
	area=compute(r, &perimeter);
	printf("\n AREA = %f", area);
	printf("\n PERIMETER = %f", perimeter);
	return 0;
}
float compute(float r, float *p)
{
	float a;
	a=(float)3.1415 * r * r;
	*p=(float)3.1415 * 2 * r;
	return a;
}

Output:

 enter the radius of the circle:5

 AREA = 78.537506
 PERIMETER = 31.415001
