(A) 1:1
(B) 2(pi):1
(C) (pi):1
(D) 1: (pi)

I got B...Is it correct?

Answer 1

Well, Let's assume the radius of a circle and the side of a square is equal to x

then the formula for the area of a circle is pi (x)^2
and the formula for a square would be x^2

pi (x)^2 : x^2 = pi : 1

Answer 2

Ohh...so it's C..
