Step-by-step explanation:

a. Area = 121 ft²

s² = 121

s = √121

Therefore s = 11 ft

b. Area = 81 yd²

s² = 81

s = √81

Therefore s = 9 yd

c. Area = 324 cm²

s² = 324

s = √324

Therefore s = 18 cm

d. Area = 361 mi²

s² = 361

s = √361

Therefore s = 19 MI

slega [8]

Answer:

$ry=\frac{rx}{2\pi }$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

Circle X

$rx=6\ units$

$Cx=12\pi\ units$

Circle Y

$Cy=6\ units$

Find the radius ry

we know that

$Cy=2\pi ry$

substitute the value of Cy

$6=2\pi ry$

$ry=\frac{6}{2\pi }$

Remember that the value of rx is $rx=6\ units$

substitute

$ry=\frac{rx}{2\pi }$
