ANSWER

C. A =9π m²

EXPLANATION

The area of a circle is calculated using the formula,

$A=\pi \: {r}^{2}$

The given circle has diameter d=6m.

To find the radius, we need to divide the diameter by 2.

$r = \frac{6}{2} = 3m$

We now substitute the given radius into formula to obtain,

$A=\pi \: {(3)}^{2}$

$A=9\pi \: {m}^{2}$

The correct answer is C.

option C

Step-by-step explanation:

You need to use the formula for calculate the area of a circle:

$A_{(circle)}=\pi r^2$

Where the radius of the circle is "r".

You can see in the figure that the diameter of the circle is 6 meters. Then you need to find the radius of the circle with the formula:

$r=\frac{d}{2}$

Where "d" is the diameter of the circle.

Then, the radius is:

$r=\frac{6m}{2}=3m$

Finally, substitute the radius into the formula. Then, the area of the circle is:

$A_{circle}=\pi (3m)^2=9\pi m^2$
