又是恶心人的水题

圆周率取3.1415926就啥事没有..

#include <iostream>
#include <cstdio>
#include <cmath>
using namespace std;
double a,b;
int n;
int main()
{    
    scanf("%d",&n);
    for(int k=1;k<=n;k++)
    {
        for(int i=1;i<=n;i++)
        {
            scanf("%lf%lf",&a,&b);
            int ans=(a*a+b*b)*(3.1415926)/100;            
            printf("Property %d: This property will begin eroding in year %d.
",k++,ans+1);
        }
        puts("END OF OUTPUT.");
    }
