The formula for the area of a circle is:

$\text{Area} = \pi * \text{(Radius)}^{2}$

The radius is the distance from the center of the circle to the edge:

In this problem, the radius of the circle is $1$

To find the area of the circle, square the radius:

$1^{2} = 1$

Now multiply by $\pi$. The number $\pi$ is approximately equal to 3.14.

$\text{Area} = \pi * \text{(Radius)}^{2}$

$\text{Area} = 3.14 * 1$

$\text{Area} = 3.14$
