Answer:

$4\pi$

Explanation:

The area of a circle is given by the formula:

$A=\pi r^2$

where

A is the area

r is the radius of the circle

In this problem we have:

r = 2 units is the radius of the circle

Therefore, substituting in the formula above, we can find the area of the circle:

$A=\pi (2)^2 = 4 \pi$

So, the area of the circle is
$4\pi$ .
