Question 10
The area of the square that can be inscribed in a circle of radius 8 cm is
(A) 256 cm2 (B) 128 cm2 (C) 64 2 cm2 (D) 64 cm2
Now,
Diagonal of square = Diameter of circle
= 16 cm
Let side of square = a cm
So,
Diagonal2 = Side2 + Side2
162 = a2 + a2
256 = 2a2
2a2 = 256
a2 = 256/2
a2 = 128
Now,
Area of square = a2
= 128 cm2
So, the correct answer is (B)
a2 = 256/2
a2 = 128
Now,
Area of square = a2
= 128 cm2
So, the correct answer is (B)
