Question

Julie is making a poster of the Earth. She wants the Earth to be a circle with a diameter of 10 inches. She wants to outline the Earth with yarn.
How many inches of yarn will Julie need to outline the Earth in her poster?

(You may use π=3.14.)

Show your work.

Answer 1

The answer is it will take 31.4 inches of yarn to outline earth.
10×3.14=31.4
She needs to know the circumference of the Earth.
So she would do pi times the diameter which is above.

31.4 inches



I hope this helps!!!!!

Answer 2

Hey there! :D

We would want to find the circumference, since she wants to outline the earth with yarn. 

C= πd

Plug in what you know. 

C= 3.14*10

C= 31.4 

She will use 31.4 inches of yarn to outline the earth. 

I hope this helps!
