Answer:

C. Circle X, circle Z, circle Y

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 = (\sqrt3)/(2)

This gives


A = (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
