Basically, if the original angle is alpha, the new value is:

(alpha*PI)/180. For example, for 90 degrees you will get:

(90*PI)/180 which is PI/2.

How do you find the arc length formed by a central angle x?

The arc length is equal to the angle times the radius. This assumes the angle is expressed in radians; if it isn't, convert it to radians first, or incorporate the conversion (usually from degrees to radians) in to your formula.


How do you convert radians to exact numbers?

the formula to convert degrees to radiansangle in radians = angle in degrees * Pi / 180 .


How do you do coterminal angles with radian measure?

The same way as with degrees. All you have to know is how to convert degrees from radians and radians from degrees.... this is how you do it... radians= pi/180 degrees= 180/pi to get angles from degrees to radians you multiply the angle that is measured in degrees by pi/180. to get angles from radians to degrees you multiply the angle that is measured in radians by 180/pi. pi=3.14


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).


How do you calculate the length of an arc of a circle?

The length of the arc is equal to the radius times the angle (angle in radians). If the angle is in any other measure, convert to radians first. (radians = degrees * pi / 180)


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).


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


How do you measure angles in radians?

well you don't get many preotractors in radians so just measure the angle in degrees. To convert this to radians you then have to divide by 180 then times by pi. This is because 180 degrees= pi radians.


What is the radian measure of an angle and how does it differ from the degree measure?

A complete circle is 360°, which is equal to 2π radians.To convert from degrees to radians, multiply by π radians per 180°.To convert from radians to degrees, multiply by 180° per π 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.


How do you rewrite each degree into radians?

-- Take the number of degrees. -- Multiply it by (pi). -- Divide the result by 180. Now you have the same angle, expressed in radians.


What is the angle 135 in radians?

There are 2.356 radians in 135 degrees of angle.
