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 = [tex]\pi r^{2}[/tex]
Since we are given the radius of the circle, we can plug 4 into our formula.
Area = [tex]\pi (4^{2})[/tex]
4² is equal to 4 x 4 which is 16.
Area = 16[tex]\pi units^{2}[/tex]
Therefore, the area of the circle is 16π units².
