Answer:
A circle with radius of 5 feet would have a circumference of
(2*5*PI) = 31.4159265359
This would mean the 7 foot arc would be (7 / 31.4159265359 ) or 0.2228169203 of the circle.
0.2228169203 * 360 = 80.2140913183 degrees
80.2140913183 degrees = 1.4 radians
and 7/5 = 1.4
Therefore the answer is the second one 7 / 5
