Calculate Circle Area: Calculate the area of the circle using the formula $A = \pi r^2$ , where $r$ is the radius. $\newline$ $A = \pi \times 3^2$ $\newline$ $A = \pi \times 9$
Substitute Pi: Substitute $3.14$ for $\pi$ to get a decimal approximation. $\newline$ $A \approx 3.14 \times 9$
Perform Multiplication: Perform the multiplication to find the area. $\newline$ $A \approx 3.14 \times 9$ $\newline$ $A \approx 28.26$
