Pologirl19 Last one please help!! A circle is inscribed in a square. Write and simplify an expression for the ratio of the area of the square to the area of the circle. For a circle inscribed in a square, the diameter of the circle is equal to the side length of the square. one year ago one year ago

1. k.rajabhishek

let side of square = a area of squre= a^2 area of circle = pie(a/2)^2

@k.rajabhishek Is the denominator a pi symbol or is it a 2 or something else. I can't decipher it.

The area of the square is side * side = 2r * 2r = 4 r ^2. The area of the circle is pi* r^2.

11. Directrix

Ratio of area of square to area of circle is: (4 r^2)/ ( pi* r^2) = 4 / pi. The ratio of square area to circle area is 4 to pi. Same as answer of @k.rajabhishek
