Question

If arc lm = 20 ft, find the radius of N

Answer 1

Answer:

120 ft

Step-by-step explanation:

60/360 or 1/6 of circle = 20 ft

full circle = 20 x 6 = 120 ft

diameter = 120/3.14 = 38.22 ft

radius = 38.22/2 = 19.11 ft

Answer 2

Answer:

Step-by-step explanation:

60° = ⅙ of 360°, so length of arc LM = ⅙ of 2πr.

20 = 2πr/6

r = 60/π ft
