Question

What is the approximate value of point Y? second picture is the answer's

Answer 1

Hello!

The answer is: A. 2π

Why?

First,  in order to make it easier, let's convert the numbers into entire or decimal numbers.

$A=2\pi=6.28\\B=2\sqrt{12}=6.92\\C=\sqrt{8}=2.82\\D=5.4$

So, ordering it:

C, D, A, B

$W=C=2.82\\X=D=5.4\\Y=A=6.28\\Z=B=6.92$

So, Y=A=6.28

Have a nice day!
