Question

Find the radius of a circle in which the central angle, a, intercepts an arc of the given length s.

a = 60°, s = 44 ft
The radius is ft.
(Round to the nearest hundredth as needed.)

Answer 1

42.02 ft

Explanation:

60 : 360 = 44 : x

x = 264 ft (length of the circumference)

C = 2 * radius * pi

radius = C / 2 * pi

Radius = 264 / 2 * pi = 42,016905 ft
