Answer: A.
$28.26\text{ units}^2$

Explanation:

From the given figure , it can be seen that the distance from the center of the circle to its boundary is 3 units.

Then, Radius of circle = 3 units

Area of circle is given by :-

$A=\pi r^2$ , where r is the radius of the circle.

Put r = 3 and
$\pi=3.14$ , we get

$A=(3.14) (3)^2=28.26\text{ units}^2$

Hence, the area of the given circle =
$28.26\text{ units}^2$
