In problem you are given full axis and if you don't want divide answer by 8, you must divide given a and b by 2 before counting integral

printf("%0.6f", number) in c/c++
or
writeln(number:0:6) in pascal

p.s. checkout the other online training/judge website
www.z-trening.com, it has more feedback when you submit a problem

This is my code...
import java.util.Scanner;

public class T_1562 {
    public static double a,b;
    public static void main(String[] args) {
        Scanner sc= new Scanner(System.in);
        a =  sc.nextDouble();
        b =  sc.nextDouble();
        b = b/2;
        a = a/2;
        int n = sc.nextInt();
        double step = 2*b/n;
        double x = -b;
        while(x+step <= b){
            System.out.printf("%.6f",Math.abs(F(x)-F(x+step)));
            System.out.println();
            x = x+step;
        }
    }
    private static double F(double z){
        return Math.PI*(a/b)*(a/b)*(b*b*z - z*z*z/3);
    }
}

I also had WA 14, I just added some digits into PI

use something like that:

Step := B/N;
Z    := -B/2;
while 1e-6 < B/2 - Z do
 begin
  WriteLn(Volume(Z, Z+Step):0:6);
  Z := Z + Step;
 end;

Integration will help you.
