The side length of a square inscribed inscribed in a circle is 2. What is the area of the circle shown at the right/

A π
B 2π
C πr2
D 22

Correct Answer: 2π

Given, Length of a side of the square = 2So,Diagonal of the square = 2×√2 = 2√2This is also the diameter of the circle So, radius = 2√2÷2 = √2Therefore, Area of the circle =π(√2)^2 = π×√2×√2= 2πAnswer : 2π
