We are given a circle of radius 2.17 cm. To determine its area we will use the following formula:

$A=\pi r^2$

Where "r" is the radius of the circle. Now we plug in the given value of the radius:

$A=\pi(2.17\operatorname{cm})^2$

Now we solve the square:

$A=4.71\pi cm^2$

Now we multiply by pi and we get:

$A=14.8\operatorname{cm}\approx14\operatorname{cm}^2$

Therefore, the area of the circle is approximately 14 square centimeters.
