Question

What is the length of CDE in degrees if the radius of circle 0 is 4? I attached the circle.

Answer 1

Answer:

12.0079  units

Step-by-step explanation:

Find the missing angle  angle  COD

360 - 27 - 103 - 50 - 35 =  180 - 35 = 145 degrees

radius is 4

the arc CDE  corresponds to the angle  CDE = 145 + 27 = 172 degrees

so   find circumference=  2*pi*4 = 8pi

arc length CDE =  (172/360)* 8*pi = 12.0079  units
