Em uma praça ha uma pista de corrida circular com 50 metros de raio um corredor deu 7 voltas completas nesta pista esse corredor percorreu aproximadamente?

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
