1. Name the Center and the radius of the following circle: *
x^2+y^2=49

Center (0, 0,) Radius 7
Center (0, 0), Radius -7
Center (0, 0), Radius -49
Center (0,0) Radius 49

a. is correct

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
