Answer: 16π units²

Step-by-step explanation: To find the area of of a circle, let's first start by writing down the formula for the area of a circle.

Area =
$\pi r^(2)$

Since we are given the radius of the circle, we can plug 4 into our formula.

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

4² is equal to 4 x 4 which is 16.

Area = 16
$\pi units^(2)$

Therefore, the area of the circle is 16π units².
