If a square is inscribed in a circle, find the ratio of the areas of the circle and the square.
When a square inscribed in a circle then,
Diameter of circle = diagonal of square
Let side of the square be = a cm
Diagonal of square be =
Area of square = a2 cm2
Diameter of circle =
؞ radius of circle =
Area of circle =
Ratio of area of circle and square =
= π : 2
