Orlov [11]

Our three numbers are...

3 3/10 = 3.3

3.1

3 1/4 = 3.25

So, if we order those from least to greatest, we have...

3.1, 3.25, 3.3

which, in the forms given, is...

3.1, 3-1/4, 3-3/10

What is the reference angle of -3 radians? Explain.
Korolek [52]

Reference angle of -3 radians is α= - 171° 53 min 15 sec .

We know the formula for calculating circular arc

Let l=circular arc which ic according to central angle of the circle α

l=((2R π)/360)α  Let l=1 radian and R=1 (unit circle with radius R=1)

1= ((2π)/360)α => α= 360/(2π)= 180/π= 57° 17 min 45sec

Angle of the 1 radian is equal to angle 57° 17min 45sec

According to this

angle of the  -3 radians = -3 ( 57° 17min 45sec) = - 171° 53min 15sec

when you count in the clockwise direction.

Good luck!!!
