Question

Emilie draws a circle with a diameter of 10 inches.Ethan draws a circle with a diameter that is half as long as the diameter of Emilie's circle.How will the circumference of Ethan's circle compare with the circumference of Emilie's circle?Explain.​

Answer 1

Answer:

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

Step-by-step 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
