The side length of a square inscribed in a circle is What is the area of the circle shown at the right?

A π

B 2 π

C πr2

D 2√2

Solution

Correct Answer: Option B

We know,

Diagonal of a square=√2×a

= √2×2

So, Radius (r)= (√2×2)/2

= √2

Therefore,

Area of the circle=πr2

= π(√2)2

= 2π (Ans.)
