Where are radians used?

Wherever you want to measure and calculate angles you can use radians


How do you calculate radians from degrees?

Scroll down to related links and use the fine calculator "Convert radians to degrees and degrees to radians".


Why do you use degrees in angles?

That's a simple way to measure angles, but later on in Calculus radians are used. 2π radians = 360o.


What is 45 degrees converted to radians?

180° = π radians → 45° = π × 45°/180° radians = π/4 radians


What is 2115 degrees in radians?

pi [radians] = 180 [degrees] 1 [degree] = pi/180 [radians] = 0.0174533 [radians] therefore, 2115 [degrees] = 2115 [degrees] * 0.0174533 [radians/degree] = 36.9 [radians]


How do you get a tangent of one?

Use an angle of pi/4 radians.


The measures of angles of a quadrilateral are in the ratio 2 3 6 7 find their measures in degrees and in radians?

The angles are: 40° = 2π/9 radians ≈ 0.698 radians, 60° = π/3 radians ≈ 1.047 radians 120° = 2π/3 radians ≈ 2.094 radians, and 140° = 7π/9 radians ≈ 2.443 radians. There are 2 + 3 + 6 + 7 = 18 parts. The sum of the angles in a quadrilateral are 360° → each part is 360° ÷ 18 = 20° → the angles are: 2 x 20° = 40° 3 x 20° = 60° 6 x 20° = 120° 7 x 20° = 140° A full circle is 2π radians → 360° = 2π radians → 1° = π/180 radians → 40° = 40 x π/180 radians = 2π/9 radians ≈ 0.698 radians → 60° = 60 x π/180 radians = π/3 radians ≈ 1.047 radians → 120° = 120 x π/180 radians = 2π/3 radians ≈ 2.094 radians → 140° = 140 x π/180 radians = 7π/9 radians ≈ 2.443 radians


Convert 16.75 radians to revolutions?

One revolution = 2Pi radians 16.75 radians / 2Pi radians/rev ~= 2.666 revolutions


What is -220 degrees in radians?

Radians = (pi/180)*degrees --> pi*(-220/180) radians = -11*pi/9 radians = -11*(3.1416)/9 = -3.839733333 radians


Convert degrees to radians 47.6925 degrees to radians?

47.6925 deg = 83.24 radians.


What is 100degrees converted into radians?

1.745 radians.


What is the symbol used to denote a measure of an angle?

When people use degrees, they either use "degrees" as in 30 degrees, or the little circle as in 30o. For Radians, they might say radians or possibly R or Rad.


How many radians in 350 degrees?

There are 6.1 radians (rounded) in 350 degrees. (6.108652 radians).


What radian measure is equivalent to negative 15 degrees?

To convert from degrees to radians, you can multiply by (pi / 180). Or use the Excel function to convert from degrees to radians. I am not sure about the name; you can find it under math functions.


What is 540 degrees in radians?

3 x pi radians as 360° is 2 x pi radians


What is the radian measure of a 315 angle?

As 180° = a straight angle = π radians → to convert degrees to radians divide by 180° and multiply by π radians → 315° = 315° ÷ 180° × π radians = 7π/4 radians ≈ 5.50 radians.


Degrees to radians?

Degrees x 0.01745 = radians


What does a zero with a horizontal line through it mean?

It means a central angle measured in radians. ex. Convert 360 degrees radians. 180 degrees = pi radians so 360 degrees = pi radians/180 degrees = 360pi radians/180 = 2 pi radians


What is 350 degrees in radians?

It is: 35/18*pi radians because 1 degree = pi/180 radians


Is 360 degrees equal to 3.14 radians?

No, 360 degrees is equal to 2 pi radians, or about 6.28 radians.


How do you convert radians to degree measures?

Multiply the number of radians by 57.3 to get the number of degrees.(The actual number is (180/pi). If you use 57.3, you're correct within 0.01%.)


How do you convert degrees to radians not in terms of pi?

Without pi, you can never represent the conversion exactly. If you use 57.296, that gets you within 0.001% of the truth, which is usually acceptable. If you use 57.3 instead, you're off by about 0.007% ... also not too shabby. Radians = approximately (degrees / 57.296) Degrees = approximately (radians x 57.296)


Convert -320 degrees to radians?

-5.58505361 radians.


How many number of radians in 90 degress are there?
