Find the area of the shaded region.​​
earnstyle [38]

There are four parts of a circle, so you have to find out the area of the circle:-

10 cm=Radius

10^{2}=100

\pi=3.14

3.14*100=314 cm^{2}

Now, find the area of the square box:-

Since half the side of the square is 10 cm, the total length of one side is 2*10 which is 20 cm.

Area=S*S

=20*20=400 cm^{2}

Now subtract the area of the box from the area of the square:-

400-314= 86 cm^{2}

That is the area of the shaded part.

Happy to help you!
