Question

Area of square is equal area if circle.Then ratio in their perimeter is

Answer 1

Answer:

a² = πr²

a²/r² = π

a/r = √π/1

4a/2πr = 4√π/2π = (2√π/π ) (Ans)

Answer 2

Since the area of the circle is PI times the square of R, and the area of the square is FOUR times the square of R (or D^2, which is the square of 2R), the ratio of the areas is: When a square is inscribed within a circle, the diagonal of the square (D) is also the diameter of the circle.
