218-20 guruh talabasi Yusupov Avazbekning Dasturlash 1 fanidan tayyorlagan 2-mavzu bo`yicha amaliy vazifasi.

Masalaning berilishi: R radiusli doiraga ichki chizilgan muntazam n-burchakning peremetri va yuzasini toping.

Masalaning yechimi:

#include

#include

using namespace std;

int main(int argc, char** argv) {

float S, P ,R ;

int n ;

cout << "R= " ;

cin >> R ;

cout << "n= " ;

cin >> n ;

S=(n * R * R * sin(2*M_PI/n)) / 2;

P=2 * n * R * sin(M_PI/n);

cout << "kiritilgan muntazam n burchakning yuzi= "<< S << endl;

cout << "kiritilgan muntazam n burchakning peremetri= "<

return 0;

}

Natija:

1)R= 3

n= 4

kiritilgan muntazam n burchakning yuzi= 18

kiritilgan muntazam n burchakning peremetri= 16.9706
