To evaluate the formula \( A = \pi r^{2} \) with \( r = 3 \), we first substitute 3 for \( r \): \( A = \pi (3)^{2} = \pi \times 9 = 9\pi \). Now, using the approximate value of \( \pi \) (3.14), we multiply: \( A \approx 9 \times 3.14 = 28.26 \). So, the area of the circle is \( 28.26 \) (rounded to the nearest hundredth).
