Have you read this post: https://gmatclub.com/forum/d01-183496-20.html#p2066045 ?


Yep just read it and found your answer where you highlighted the three properties.

Thanks!

I think this is a poor-quality question and I agree with explanation.

I read this question 5 times before I realized it wanted a circle with an area of 154.

SOOOO tricky.

The question asks about the approximate length.

\(\pi = 3.1415...\) and 22/7 = 3.142..., and since we need only approximate value we can use 22/7 instead of \(\pi\) to simplify calculations.



One would need to remember that 22/7 is the approximate value of 3.14.. That's where I went wrong.
