Acircle and a square have the same area. what is the ratio of the radius of the circle to the side of the square

Step-by-step explanation:

if the circle’s radius is r, and the side of the square is a, then for the area of the circle and the square we have, respectively:

S1=πr2

S2=a2

But, according to the problem statement

S1=S2=>πr2=a2=>a2r2=π=>(ar)2=π

Therefore, the ratio of the side of the square and the radius of the circle is

ratio=(ar)=π−−√

answer: 25 is the correct answer
