It should be 12×18. 1:3 means you take where it's at, at 1 and multiply it's size by 3.

12.22

Step-by-step explanation:

There are 360° in a full circle

The circumference of a circle is c = 2πr

The lenght of the arc will be the portion of the circumferece included in the angle

l = (∅/360) * 2πr

plug in the knowns

l = (70/360) * 2π(10)

l ≈ 12.22
