Answer 1

A

Answer 2

The answer is B.
What you have to remember is that Circumference = 2 x pi x r
so it is 2 x pi x 18. This equals 36 pi and is so B.

Answer 3

You're right but It doesn't say if it should be in terms of pi or not so I think it's just a funky question.

Answer 4

@Novalynne I just found my mistake, if you have 36 pi is actually 113.09. So the actual answer is A!.
