Answer:

19.6 cm²

Step-by-step explanation:

If a circle fits perfectly inside of a square, then its diameter is equal to the length of sides of the square.

The area of a circle is given by:

A= \pi \frac{d^2}{4}

In this problem, d = 5 cm, the area of the circle is:

A= 3.14 *\frac{5^2}{4} \\A=19.6\ cm^2

The approximate area of the circle is 19.6 cm².
