Question

What is the approximate area of the circle shown below?

Answer 1

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

Answer 2

Answer: The correct option is D.

Step-by-step 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,

`2r=d`

`2r=18`

`r=9`

Therefore, the radius of the circle is 9 cm.

The formula to find the area of the circle is,

`A=\pi r^2`

`A=\pi (9)^2`

`A=\pi (81)`

`A=254.469\approx 254`

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