Consider that the area (A) of a circle having radius R units, is given by the formula,


A=\pi R^2

According to the given problem, the radius of the circle is 4 units,


R=4

Then the corresponding area of the circle is calculated as,


\begin{gathered} A=\pi(4)^2 \\ A=\pi(16) \\ A=16\pi \end{gathered}

Substitute the value of the constant π in the expression,


\begin{gathered} A=16\cdot(3.14) \\ A=50.24 \end{gathered}

Thus, the area of the circle is 50.24 sq. units approximately.
