For students only reference, prohibit copying!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 #include <iostream> #include  <math.h> using  namespace   Std;  int   Main () { double   A,b,c;    CIN  >>A; b  =2  *a*3.14159  ;    C  =a*a*3.14159   <<b<< "  <    <c<<ENDL;  return  0  ;}  

finding the circumference and area of a circle

#include <iostream>#include<math.h>usingnamespace  std; int Main () {    double  n,a,b;    CIN>>N;    A=n*n*6;    b=n*n*n;    cout<<a<<""<<b<<Endl;     return 0 ;}

the surface area and volume of the cube

#include <iostream>#include<math.h>using namespacestd;intMain () {Doubler,a,b; CIN>>R; A=4*3.14*r*R; b=(4.0/3)*3.14*r*r*R; cout<<a<<" "<<b<<Endl; return 0;}

calculating the surface area and volume of the ball

#include <iostream>#include<cmath>usingnamespace  std; int Main () {    float  s1,s2,h,v;    CIN>>s1>>s2>>H;    V= (s1+sqrt (s1*s2) +s2) *h/3;    cout<<v<<Endl;     return 0 ;}

find the volume of the Round table

#include <iostream>#include<math.h>usingnamespace  std; int Main () {    double  r,h,v;    CIN>>r>>H;    V= (1.0/3) *r*r*3.14*h;    cout<<v<<Endl;     return 0 ;}
