Convert -18pi/5 Radians to Degrees

Divide the angle in rad by pi, then multiply the term by 180° using the formula deg = ([-18pi/5] / pi) × 180°. Thus, you get (rounded to ten decimal places):

-18pi/5 rad = -648°

Frequently Asked Questions

What is -18pi/5 radians in terms of pi?

An angle of -18pi/5 radians cuts off an arc of length -18pi/5r 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: -18pi/5 rad = degrees / 180° x pi.

Where is -18pi/5 radians on unit circle?

The angle of -18pi/5 radians lies in the first quadrant, between 0 and pi/2.

What is the angle measure of -18pi/5 radians?

-18pi/5 exact radians is equal to -18pi/5 / pi × 180° = -648°.

How many degrees in -18pi/5 radians?

-18pi/5 rad = -18pi/5 / pi × 180° = -648 degrees.

What’s bigger -18pi/5radian or -18pi/5 degree?

A circle has a little more than six radians, yet 360 degrees. Thus, -18pi/5 radians much bigger than -18pi/5 degrees.

What is -18pi/5 radians converted to degrees?

-18pi/5 radians converted to degrees equals -648 degrees.

How to convert -18pi/5 radians to degrees?

To convert -18pi/5 radians to degrees divide the angle in radians by pi, then multiply the term by 180°: degreees = -18pi/5/ pi × 180°.

What quadrant is -18pi/5 radians?

Because each quadrant has pi/2 radians we divide the coterminal angle of -18pi/5 by pi/2: 2pi/5 / pi/2 = 0.8, then round this term up to nearest whole number between 1 and 4: 1. Thus, -18pi/5 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.
