Answer:

41.2 cm^2

Step-by-step explanation:

Square area = 8x8 = 64 cm^2

The sum of the 4 white areas is a circle of radius r = 4cm

The area of the circle is [tex]\pi r^{2} = 16\pi = 22.8 cm^2[/tex]

The yellow region is the difference = 64 - 22.8 = 41.2 cm^2

Answer:

13.8 sq.cm

Step-by-step explanation:

Area of shaded region = area of square - area of 4 quater circles

(4 quater circles=1 circle)

= area of square - area of one circle

= s^2 - πr^2

= 8×8 - 3.14 × 4×4 (r = 4cm because radius is half of the side of square)

= 64 - 3.14 ×16

= 64 - 50.24

= 13.76

Nearest tenth of 13.76 is 13.8
