Multiple Functions Within A Program

[M_A_T_T]

Hi I am getting an error on lines 31 and 36 about an expected identifier on my program that computes area and circumference. Is something wrong with my external functions outside of main? Thank you.

#include <stdio.h>
#define PI 3.14159

double area;
double circum;

double find_circum (double radius);
double find_area (double radius);


int
main(void)
{
      double radius;

      /* Get the circle radius */
      printf("Enter radius> ");
      scanf("%lf", &radius);

      area = find_area(radius);
      circum = find_circum(radius);

      printf("The area is %.4g\n", area);
      printf("The circumference is %.4g\n", circum);

}

      double find_area (double radius);
      {
      return PI * radius * radius;
      }

      double find_circum (double radius);
     {
      return 2.0 * PI * radius;
     }

      double find_area (double radius);
      {
      return PI * radius * radius;
      }
 
      double find_circum (double radius);
     {
      return 2.0 * PI * radius;
     }
