Siam Problem 2 Fixed

#include <stdio.h>

void calArea(double *radius) {
    double x = (*radius);
    double area = (3.1416 * x * x);
    double perimeter = (2 * 3.1416 * x);
    printf("Area = %.2lf\n", area);
    printf("Perimeter = %.2lf\n", perimeter);
}

int main() {
    double radius;
    printf("Enter the radius of the circle\n");
    scanf("%lf", &radius);
    calArea(&radius);
}
