using namespace std;

int main()

long double straal;
string answer;
long double opp;
long double pi;

cout<<"Hello there enter your radius \n";
cin >> straal;
cout <<"Good would you like pi 3.14 or pi 3.14159265 \n";
cout <<"Type yes for 3.14 or type no for 3.14159265 \n";
cin >> answer;

if(answer == "yes"){
pi = 3.14;
straal = straal*straal;
opp = pi*straal;
cout << "Your answer is "<<opp;

}

if(answer == "no"){
pi =3.14159265;
straal = straal*straal;
opp = pi*straal;
cout <<"Your answer is "<<opp;
}
