S = r·α is the formula to find the arc length (s), given the radius (r), and angle measure (α) in radians.
If the angle measure is NOT given in radians you must convert to radians.
s = 8 · 2.6
s = 20.8 in

Answer:

Step-by-step explanation:
Given the system of two equations:

Multiply the first equation and the second equation by 60 to get rid of fractions:

Now multiply the first equation by 4 and the second equation by 5:

Subtract them:

Substitute it into the first equation:

The solution is
12m-32=-80
12m=-80+32
12m=-48
m=-4
