C :

#include <stdio.h>

#define PI 3.1415926535

int main(void) {
	double r;
	scanf("%lf", &r);
	printf("%.2f\n%.2f\n", PI*r*r*4, (PI*r*r*r)*((double)4/(double)3));
	return 0; 
}

C++ :

#include<cstdio>
using namespace std;
int main()
{
       double h,r,pi,s,v;    
       scanf("%lf",&r);  
       pi=3.1415926535; 
       s= pi*r*r  *4   ;
       v= pi*r*r*r  *(4.0/3.0);
       printf("%.2lf\n",s);    
	printf("%.2lf\n",v);   
       return 0; 
}

Pascal :

Program ygjsb;
const pi=3.1415926535;
  Var
   r,v,s:real;
  begin
   read(r);
   v:=pi*r*r*r*4/3;
   s:=4*pi*r*r;
   writeln(s:0:2);
   write(v:0:2);
  end.
