To find the area of the circle, we first need to determine the radius. The radius \( r \) is half of the diameter.

Given:
- Diameter = 8 cm

So, the radius \( r \) is:
\[
r = \frac{8}{2} = 4 \text{ cm}
\]

Now, we can use the area formula \( A = \pi r^2 \).

Substituting in the values:
\[
A = 3.14 \times (4)^2
\]
\[
A = 3.14 \times 16
\]
\[
A = 50.24 \text{ cm}^2
\]

Therefore, the area of the circle, rounded to the nearest hundredth, is:
\[
\boxed{50.24}
\]
