Пицца, диаметр которой равен 30 см, стоит столько же, сколько две пиццы диаметром 20 см. В коком случае Николай съест больше пиццы: если купит одну большую или две маленькие, если все пиццы имеют одинаковую толщину.

если купит одну большую пиццу так как:

2 пиццы = (20×20)+(20×20)=800 см

1 большая пицца = 30×30=900 см

ЛУЧШИЙ ОТВЕТ

Для тебя старалась! many people think that wild animals, living in jungles, forests and mountains, are cruel, and animals living in the zoo are kind, funny and they are real peoples' best friends. but it's not like that. not everyone knows that these animals aren't happy to live in the zoo because they live there like in prison. people that come to see them on the weekends often feed animals with food which is not good for them, and after that monkeys, bears and others are falling ill. animals are afraid of their masters as they beat them in cages to be calm and obedient. and every day they have to do things they don't like.   animals can't run and jump as the like because they are not free. the zoo also travel very often from one town to another. it's very hard for poor animals. we can't forget that we should take care of animals because they are our little brothers and friends. we should be responsible for them, and let them live in their native places - in jungles, forests and mountains as they are free there and happy.
