B. Circle Y, circle Z, circle X
C. Circle X, circle Z, circle Y
D. Circle X, circle Y, circle z

Answer 1

Answer:

C. Circle X, circle Z, circle Y

Step-by-step explanation:

Given

Circles X, Y and Z

Required

Order from greatest to highest

First, we need to simplify the given areas;

For Circle X

$A = 9\pi$

Take $\pi$ as 3.14

$A = 9 * 3.14$

$A = 28.26$

For Circle Y

$A = \frac{\sqrt3}{2}$

This gives

$A = \frac{1.732}{2}$

$A = 0.866$

For Circle Z

$A = 27.5$

By comparing the above areas;

X has the largest area; followed by Z and then Y

Hence,

option C answers the question
