Answer:

The circumference of Ethan's circle is half the circumference of Emilie's circle

Explanation:

we know that

Emilie's circle

$D=10\ in$

The circumference is equal to

$C=\pi D$

$C=\pi (10)$

$C=10\pi\ in$

Ethan's circle

$D=10/2=5\ in$

The circumference is equal to

$C=\pi D$

$C=\pi (5)$

$C=5\pi\ in$

therefore

The circumference of Ethan's circle is half the circumference of Emilie's circle
