Answer:

Step-by-step explanation:
Slope = change in y ÷ change in x
The line passes through (3,7) and (-1,4)
Slope =
= 
Get a common denominator. Which is 24. So the answer is going to be 11/24 or in decimal form: -0.4583
Formula to find the central angle is,

Where, s = arc length
r = radius
= central angle in radian.
According to the given problem,
r = 7 and
.
First step is to plug in these values in the above formula. So,

By simplifying.
Since 

s=14.65
Hence, arc length iss 14.65 feet.
