Which of the following are in correct order from greatest to least? pi/2, 330°,5pi/3 ,7pi/6 ,2pi/3 5pi/3,7pi/6 ,2pi/3 , pi/2 , 330° pi/2, 2pi/3 , 7pi/6, 5pi/3, 330° 330°, 5pi/3, 7pi/6,2pi/3 , pi/2 (answer is D)

D) 330°, 5π/3 , 7π/6 , 2π/3 , π/2

Step-by-step explanation:

Lets clear the question first. We have been given 4 options:

A) π/2 , 330°, 5π/3, 7π/6, 2π/3

B) 5π/3, 7π/6 , 2π/3 , π/2 , 330°

C) π/2, 2π/3 , 7π/6, 5π/3, 330°

D) 330°, 5π/3 , 7π/6 , 2π/3 , π/2

Lets convert all the values into degrees

330° = 330°

π/2 = 180/2 = 90°

5π/3 = 300°

7π/6 = 210°

2π/3 = 120°

Arrange them from greatest to lowest.

330° , 300° , 210° , 120° , 90°

or

330° , 5π/3 , 7π/6 , 2π/3 , π/2

which is option D

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
