the length of segment AB is 13
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
80+70=150
270/150=1.8 hours before the two trains are 270 miles apart
