Question

A circle is drawn inside a square so that the edge of the circle touches the midpoint of each side of the square, as shown below. The radius of the circle is 84cm.
Calculate the total area of the four shaded sections.
Give your answer in cm^2 to 1 d.p.

Answer 1

the side of the square is 2 R = 168 cm
so the area of the square is 28,224 cm^2
the area of the circle is pi R^2 = 22,167 cm^2
the difference is 6056.94
I am just guessing that is what is asked for. Of course I can not see your figure with its shading.

Answer 2

1176.5 cm^2
