ANS:1:2
EXPLANATION:
If a circle is circumscribed around a square, the area of
the circle is π / 2 (about 1.57) times the area of the
square.
If a circle is inscribed in the square, the area of the
circle is π / 4 (about 0.79) times the area of the square.
SO,
Ratio of area of inner to outer circle is,
=(pi/2*a^2)/(pi/4*a^2)
= 1/2
Ans=1:2
