A circular arc of length 5 ft subtends a central angle of 50°. Find the radius of the circle. (Round your answer to two decimal places.)

Answer:

Given: circle with
Central angle θ=50°
Arc length L=5 ft

The arc length is the circumference of a circle multiplied by the ratio of the central angle to 360° (since a full circle has an angle of 360°).
