The formula for the area \(A\) of a circle is:

\[
A = \pi r^2
\]

Where:
- \(r\) is the radius of the circle.
- \(\pi\) is approximately 3.14159.

Given the radius \(r = 5\):

\[
A = \pi (5)^2 = \pi \times 25 \approx 3.14159 \times 25 = 78.54 \, \text{square units}.
\]

So, the area of the circle is approximately **78.54 square units**.
