Acircle has a radius of 10 inches. find the approximate length of the arc intersected by a central angle of 2pi/3

You can solve this problem and calculate the arc lenght, by applying the following formula:

 s=θr

 s: it is the arc lenght.
 θ: it is the central angle (θ=2π/3).
 r: it is the radius of the circle (r=10 inches).

 When you substitute these values into the formula, you obtain the arc lenght (s):

 s=θr
 s=(2π/3)(10)

 Then, you have that the value of the arc lenght is:

 s=20.94 inches
