Convert 2pi/9 Radians to Degrees
Divide the angle in rad by pi, then multiply the term by 180° using the formula deg = ([2pi/9] / pi) × 180°. Thus, you get (rounded to ten decimal places):If you need the outcome with higher accuracy, then make use of our calculator above, or employ a calculator of your own and our formula.

Frequently Asked Questions
What is 2pi/9 radians in terms of pi?
An angle of 2pi/9 radians cuts off an arc of length 2pi/9r when placed at the center of a circle with the radius r; the relationship with pi can only be determined if the angle in degrees is known: 2pi/9 rad = degrees / 180° x pi.
Where is 2pi/9 radians on unit circle?
The angle of 2pi/9 radians lies in the first quadrant, between 0 and pi/2.
What is the angle measure of 2pi/9 radians?
2pi/9 exact radians is equal to 2pi/9 / pi × 180° = 40°.
How many degrees in 2pi/9 radians?
2pi/9 rad = 2pi/9 / pi × 180° = 40 degrees.
What’s bigger 2pi/9radian or 2pi/9 degree?
A circle has a little more than six radians, yet 360 degrees. Thus, 2pi/9 radians much bigger than 2pi/9 degrees.
What is 2pi/9 radians converted to degrees?
2pi/9 radians converted to degrees equals 40 degrees.
How to convert 2pi/9 radians to degrees?
To convert 2pi/9 radians to degrees divide the angle in radians by pi, then multiply the term by 180°: degreees = 2pi/9/ pi × 180°.
What quadrant is 2pi/9 radians?
Because each quadrant has pi/2 radians we divide 2pi/9 by pi/2 = 0.444444444444444, then round this term modulo 4 up to nearest whole number between 1 and 4: 1. Thus, 2pi/9 rad lies in the first quadrant.

Additional information
The positive movement of an angle in a circle is a counterclockwise revolution, and the angular measure is indicated in either of these units: rad, deg or grad (gradians).The magnitude in radians tells you how far you have traveled on the arc. Try to remember that whenever you deal with radians or the other circular measure.
More information about the term radian, the entire circle, the diameter as well as the complete revolution can be found in radians to degrees.
