In the given figure ABCD is a square and C is the center of the circle. If the area of square is 8, what is the area of circle.


A. 
64π 

B. 
32π 

C. 
8π√2 

D. 
8π 

E. 
16π 
See Answer & Explanation
Lets Discuss
Correct answer is : E
Explanation Area of square = 8
so one side of square = √area = √8 = 2√2
If one side of a square is a then diagonal would be a√2 = 2√2*√2 = 4
Now we know that diagonal of the square is nothing but the radius of the circle so area of circle as per formula π*(radius)^{2} = π * 4^{2 }= 16π
