To find the area of a circle, you can use the formula:
\[
\text{Area} = \pi r^2
\]
where \( r \) is the radius of the circle.
Given that the radius \( r \) is 3 cm, the area of one circle can be calculated as follows:
\[
\text{Area} = \pi (3 \, \text{cm})^2 = \pi \times 9 \, \text{cm}^2 = 9\pi \, \text{cm}^2
\]
For two circles, you would multiply the area of one circle by 2:
\[
\text{Total Area} = 2 \times 9\pi \, \text{cm}^2 = 18\pi \, \text{cm}^2
\]
Therefore, the area of two circles with a radius of 3 cm is \( 18\pi \, \text{cm}^2 \).
If you want a numerical approximation, you can use \( \pi \approx 3.14 \):
\[
\text{Total Area} \approx 18 \times 3.14 \approx 56.52 \, \text{cm}^2
\]
Thus, the total area of the two circles is approximately \( 56.52 \, \text{cm}^2 \).
