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

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

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

hi how are you doing today, if you need just ask me.
