Step1: Analyze the sentence structure

The sentence says "The area \(A\) of a circle is pi times the radius \(r\) squared".

Step2: Translate each part into symbols

"Is" can be translated as "=" in a formula. "Pi" is represented by the symbol \(\pi\). "The radius \(r\) squared" is \(r^{2}\).

Answer:

\(A = \pi r^{2}\)
