Code:
/* Homework Two- compute area and volume of sphere */ 
#include <stdio.h> 
#include <math.h> 
#define pi = 3.141593 
main() 
{ 
double Area, Radius, Volume, pi; 
int r; 
int k; 
for(r=1; r<=1; r++); 
for(k=10; k<=20; k++); 
{ 
Radius=((k)*(.1)); 
Area=(pi*(Radius)*(Radius)); 
Volume=((4/3)*pi*(Radius)*(Radius)*(Radius)); 
printf("\n"); 
printf("Sphere (%2d)\tRadius = %4.1f\tArea = %7.3f\tVolume = %7.3f",r,Radius,Are

I'm getting parse errors, they are as follows...

:Hw2.c: In function `main':
Hw2.c:7: parse error before '=' token
Hw2.c:14: parse error before '=' token
Hw2.c:14: parse error before ')' token
Hw2.c:15: parse error before '=' token
Hw2.c:15: parse error before ')' token

Any help would be appreciated, thanks
