Question

Find the area of the circle.

Answer 1

Answer:

C. 254.34 in^2

Step-by-step explanation:

The formula for area of a circle is πr² (pi x radius x radius).

Here, only the diameter is shown.

To find the radius, divide the diameter by 2.

18 / 2 = 9

9 is the radius.

We use 3.14 as π (pi).

Now we have the final equation.

pi x radius x radius

3.14 x 9 x 9 = 254.34 in^2.

Therefore, the area of the circle is 254.34 in^2.

Answer 2

Answer:

have of 18 is 9

9^2 is 81

81 x 3.14(pi) = 254.34

Formula of area of a circle:

half of diameter or given radius squared

Times

3.14(pi) or whatever you use for pi.
