Answer:

The area of the circle depends of the square of the radius

The area of the circle D is [tex]324 \pi\ cm^{2}[/tex]

Step-by-step explanation:

we know that

The area of the circle is equal to

[tex]A=\pi r^{2}[/tex]

In this problem we have

[tex]r=CD=18\ cm[/tex]

substitute

[tex]A=\pi (18)^{2}=324 \pi\ cm^{2}[/tex]

therefore

the statements that are true are

The area of the circle depends of the square of the radius

The area of the circle D is [tex]324 \pi\ cm^{2}[/tex]
