The area of a square inscribed in a circle of radius 8 cm is
A) 32 sq cm
B) 64 sq cm
C) 128 sq cm
D) 256 sq cm
Correct Answer:
C
Solution :
Given that, Radius of a circle = 8 cm \[\therefore \]Diameter of a circle =16 cm \[\Rightarrow \]Length of a diameter of a square = Diameter of a circle (given) \[\Rightarrow \] \[a\sqrt{2}=16\] \[\therefore \] \[a=8\sqrt{2}\,\,\text{cm}\] \[\therefore \]Area of square ABCD \[={{a}^{2}}={{(8\sqrt{2})}^{2}}\] \[=64\times 2=128\] sq cm
