Answer:
4/pi
Explanation:
The area of the square is
A = s^2
The area of the circle is
A = pi r^2
The diameter of the circle is s, we need to find the radius
d = 2r
s =2r
Divide by 2
s/2 = r
A = pi *(s/2) ^2
A = pi (s^2/4)
We want the ratio of the A square/ A circle
s^2/ pi (s^2/4)
The s^2 cancels
1/ pi (1/4)
4/pi
