What is the area of this circle ( express your answer by using pi)

a. a=3 pi m²

b. a=6 pi m²

c. a=9 pi m²

d. a=36 pi m²

option C

Step-by-step explanation:

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

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:

Where "d"  is the diameter of the circle.

Then, the radius is:

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

ANSWER

C. A =9π m²

EXPLANATION

The area of a circle is calculated using the formula,

The given circle has diameter d=6m.

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

We now substitute the given radius into formula to obtain,

The correct answer is C.
