Respuesta :

Area = pi * radius²
Area = 3.14159 * 9²
Area = 3.14159 * 81
Area = 254.46879
answer is D


Answer: The correct option is D.

Explanation:

From the given figure it is noticed that the point C is the center of the circle and the length of the diameter is 18 cm.

We know the diameter is twice of the radius,

[tex]2r=d[/tex]

[tex]2r=18[/tex]

[tex]r=9[/tex]

Therefore, the radius of the circle is 9 cm.

The formula to find the area of the circle is,

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

[tex]A=\pi (9)^2[/tex]

[tex]A=\pi (81)[/tex]

[tex]A=254.469\approx 254[/tex]

Therefore, the D is the correct option. The area of the circle is 254 cm square.
