Question

Find the length of the arc intercepted by a central angle of 240 degrees in a circle of radius r equals 9 feet

Answer 1

Answer:

37.7 feet ( to 1 dec. place )

Step-by-step explanation:

arc length = circumference × fraction of circle

                 = 2π r × $\frac{240}{360}$

                 = $\frac{2\pi (9)(240)}{360}$ ≈ 37.7 feet
