To calculate 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 diameter of the circle is 7 cm, the radius \( r \) is half of the diameter:
\[
r = \frac{7 \text{ cm}}{2} = 3.5 \text{ cm}
\]
Now, substitute the radius into the area formula:
\[
\text{Area} = \pi (3.5 \text{ cm})^2 = \pi (12.25 \text{ cm}^2) \approx 38.48 \text{ cm}^2
\]
So, the area of the circle is approximately **38.48 square centimeters**.
