Program liczący pole i obwód koła z podanego promienia. Oblicza również równanie kwadratowe.
W karcie Koło podajemy w obszarze Dane promień koła, następnie klikamy oblicz i program oblicza pole i obwód koła.
W karcie Równanie kwadratowe w obszarze Dane podaje a, b i c, następnie klikamy Oblicz, program obliczy x1, x2 i deltę.
