How do you convert 18 degrees to radians expressing the answer as a multiple of pi?

A radian is an arc of a circle whose size is the same as its radius and in degrees it is about 57.3 degrees because there are 360 degrees around a circle and so 2*pi radians = 360 degrees.
2 pi = 360 degrees
therefore 18 degrees = 2 pi x 18/360 radians
= 0.1 pi radians

How do you convert between radians and degrees using an Aurora calculator?
-- Multiply radians by ( 180/pi ) to get degrees. -- Multiply degrees by ( pi/180 ) to get radians. This technique works with any brand of calculator. Also with computers, Curta, pencil and paper, and slide rules.
How do you find the angle with the radius and the arc length?
The arc length divided by the radius is the angle in radians. To convert radians to degrees, multiply by (180/pi).
How do you find the measure of angle 75 degree in radians?
A full turn is 360° which is equivalent to 2π radians To convert form degrees to radians divided by 360° and multiply by 2π; however 360° = 180°×2, therefore divide by 180° and multiply by π radians. → 75° = 75° ÷ 180° × π radians = 5π/12 radians ≈ 1.31 radians
How would you convert an angle in degrees to angle in radians?
Divide the angle measured in degrees by (180/pi). Alternatively, multiply by (pi/180).
