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
All i know is that both of them are parallel
i think for the first one its 6
hope this helps
G(x)=10 because they g goes into c
divide 63 by9
63 / 9 = 7
each piece is 7 meters long
