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, and using \( \pi \approx 3.14 \):
\[ \text{Area} = 3.14 \times (3)^2 \]
Calculating \( (3)^2 \):
\[ (3)^2 = 9 \]
Now substitute back into the area formula:
\[ \text{Area} = 3.14 \times 9 \]
Multiplying:
\[ 3.14 \times 9 = 28.26 \text{ cm}^2 \]
Thus, the area of the circle is:
\[ \boxed{28.26 \text{ cm}^2} \]
The correct answer is B. 28.26 cm².
