Answer:

[tex]ry=\frac{rx}{2\pi }[/tex]

Step-by-step explanation:

we know that

The circumference of a circle is equal to

[tex]C=2\pi r[/tex]

we have

Circle X

[tex]rx=6\ units[/tex]

[tex]Cx=12\pi\ units[/tex]

Circle Y

[tex]Cy=6\ units[/tex]

Find the radius ry

we know that

[tex]Cy=2\pi ry[/tex]

substitute the value of Cy

[tex]6=2\pi ry[/tex]

[tex]ry=\frac{6}{2\pi }[/tex]

Remember that the value of rx is [tex]rx=6\ units[/tex]

substitute

[tex]ry=\frac{rx}{2\pi }[/tex]
