Question

I need help pls my other question won’t let me add a picture

Answer 1

SoluTion :-

$\sf {Area\ of\ square = Side^{2}}\\\\\\\sf {Area\ of\ square = 12^{2}=144\ cm^{2}}\\\\\\\\\sf {Radius\ of\ Circle_{1}=3\ cm}\\\\\\\sf {Area\ of\ Circle=\pi r^{2}}\\\\\\\sf {Area\ of\ Circle=3.14 \times 3^{2}=28.27\ cm^{2}}\\\\\sf {Total\ area\ of\ 2\ circles = 28.27(2)=56.54\ cm^{2}}\\\\\\\\\sf {Area\ of\ shaded\ region = 144-56.54=87.46\ cm^{2}}$

Answer 2

Step-by-step explanation:

Side of square = 12cm

Area of square = (12)^2 = 144cm^2

Radius of circle = 3cm

Area of circle = πr^2 = 3.14×(3)^2

= 3.14×9 = 28.26cm^2

Therefore, area of second circle = 28.26cm^2

So, Area of shaded region = 144 - 2(28.26) = 144 - 56.52

= 87.48cm^2
