To solve the problem of finding the area of a circle with a radius of 5 cm, follow these steps:

Step 1: Recall the formula for the area of a circle

The area (A) of a circle is given by:
[A = \pi r^2]
where (r) is the radius, and (\pi \approx 3.14) (a constant).

Step 2: Substitute the radius into the formula

Given (r = 5) cm:
[A = \pi (5)^2 = 25\pi]

Step 3: Calculate the numerical value (if needed)

Using (\pi \approx 3.14):
[A \approx 25 \times 3.14 = 78.5]

Final Answer:
The area is either (\boxed{25\pi}) cm² (exact form) or (\boxed{78.5}) cm² (approximate value).

(Commonly, the approximate value is used unless exact form is specified.)

(\boxed{78.5}) cm² (or (\boxed{25\pi}) cm²) is the solution.

Answer: (\boxed{78.5}) (or (\boxed{25\pi}))

(Assuming numerical approximation is required, the final answer is (\boxed{78.5}).)

(\boxed{78.5})
