To find the area of a circle, you use the formula:
\[ \text{Area} = \pi r^2 \]
For a circle with a radius \( r = 3 \):
\[ \text{Area} = \pi (3^2) = \pi \times 9 \]
So, you find the area by multiplying \( \pi \) by 9. Therefore, the answer to the first question is none of the provided options (66 or 99).
As for the second question, we can compute the area more specifically:
Using \( \pi \approx 3.14 \):
\[ \text{Area} \approx 3.14 \times 9 \approx 28.26 \]
Therefore, for your second question, the correct answer is:
C 28.26
