Asquare and a circle intersect so that each side of the square contains a chord of the circle equal in length to the radius of the circle. what is the ratio of the area of the square to the area of the circle? express your answer as a common fraction in terms of $\pi$.

1/π

Step-by-step explanation:

r = the side of the square and the radius of the circle

square area = r∧2/π·r∧2

r∧2 should cancel each other in the numerator and denominator.

The result is 1/π

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
