1/2 can be rewritten as 3/6, and 2/3 can be rewritten as 4/6 (find the lowest common denominator and in this case it is 6 because 2x3=6). 3/6+4/6=7/6. 12 can rewritten as 24/6, so do 24/6 - 7/6 and you answer is 17/6.

Step-by-step explanation:
Answer:
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
