Fix the error and re-write the code: #include ; int main()  { float radius, area,    float circumference;  printf("To calculate the radius & circumference of a circle: ");  scanf("Enter the radius of the circle: %f", &radius);   area == 3.14 * radius * radius;   circumference = 2 * 3.14 * radius;   printf("\nThe area of the circle is %lf", area);   printf("\nThe circumference of the circle is %lf", circumference);   return 0;  }
