Calculate the area of a circle inscribed in a square if the side of the square is 8cm long.

As we know from the school mathematics course, the radius of a circle (circle) that is inscribed in such a geometric figure can be calculated through its side divided by two.

Let’s determine what the radius of the circle that was inscribed in the square will equal, when from the condition of the task we know that its side is 8 centimeters:

8: 2 = 4.

Let us determine what the area of such a circle will be, for which we take the default value of π equal to 3.14:

3.14 * 4 * 4 = 3.14 * 16 = 50.24.

Answer: 50.24 cm2.
