A circle 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
