  1. A circle is inscribed in an equilateral triangle and a square is inscribed in that circle. The ratio of the areas of the triangle and the square is
    1. 3 : 4
    2. 3 : 8
    3. 3√3 : 2
    4. 3√3 : 1
Correct Option: C


Let AB = BC = CA = x units, then

AD = √x² -
=
3x
42

OD =
1
AD =
x
= radius of circle
32√3

⇒ Diagonal of square = 2 ×
x
=
x
2√33

∴ Triangle : Square
=
3
x² :
42 × 3

=
3
:
1
= 3√3 : 2
23
