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!!!!!

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!
