Find the length of the arc s on a circle of radius r interce

Find the length of the arc, s, on a circle of radius r intercepted by a central angle theta. Express the arc length in terms of pi. Then Radius. r = 8 inches; Central angle, theta = 140 degree s = inches (Simplify your answer. Type your answer in terms of x. Use integers or fractions for any numbers in the expression.) s = inches (Type your answer rounded to two decimal places.)

r=8 inches

theta=140 degree=140 *pi/180=7pi/9 radians
