Answer:

19.6 cm²

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 (d^2)/(4)

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


A= 3.14 *(5^2)/(4) \\A=19.6\ cm^2

The approximate area of the circle is 19.6 cm².
