The equation is -3x/y
Plug in the numbers given for x and y
-3(10)/-3.5
-30/-3.5
divide and that's your answer

Answer:
 = 5/3 * pi  inches
   or approximately 5.235987756 inches
Step-by-step explanation:
The formula for arc length = r * theta  where theta is in radians
arc length = 10 * pi/6
                  = 10/6 * pi
                 = 5/3 * pi
                 or approximately 5.235987756 inches
