Answer:
223.75 cm²
Step-by-step explanation:
In the figure ABCD is a square inside the circle whose vertices lie on the circle.
The perimeter of the circle = 88 cm
2πr = 88
r=\dfrac{88\cdot 7}{2\cdot 22}r=
2⋅22
88⋅7
r=14r=14 cm
Diameter of circle = 2r
= 2×14
= 28 cm
Diameter of circle is equal to diagonal of square.
Let side of square be x cm
Length of diagonal =x\sqrt{2}=x
2
So, x\sqrt{2}=28x
2
=28
x=14\sqrt{2}\ cmx=14
2
cm
Area of square =x^2=x
2
Area of square, A_S=(14\sqrt{2})^2=392\ cm^2A
S
=(14

)
2
=392 cm
2
Area of circle =\pi r^2=πr
2
Area of circle, A_C=\pi \cdot 14^2=615.75\ cm^2A
C
=π⋅14
2
=615.75 cm
2
Area of shaded region = Area of circle - Area of square
= 615.75 - 392
