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.
