Best Answer

For a circle, 2 pi r is the circumference of a circle. If you imagine yourself standing at the center of a circular race track, to follow a car going around the track once, you would have to rotate 360 degrees, which in radians is expressed as 2pi. Radians is basically another measure for degrees based on the circumference of a circle. since 180 degrees is one half of a full rotation on half of a full rotation in radians (2pi) should = pi.

How do you convert degrees to radians?

pi = 3.14 pi rad = pi * 1 randian 360 degrees = 2pi rads 180 degrees = pi rads rads = (degree * pi) / 180 degrees = (rad * pi) / 180 If pi rad = 180 degrees, the 1 rad must = 180/pi If pi rad = 180 degrees, then 1 degree must = pi rads / 180 Keep following through.


What is the degree of exactness of measurement?

360 degrees equals 2(pi) radians. Therefore, [2(pi)](623/360) = (623/180)(pi). Since I have not discovered any common integral factor for 623 and 180, I believe this is the simplest manner in which the exact radians measure can be written.

How do you convert degrees into radians?

There is no word such as raduis. The nearest word that makes the question sensible is radians. To convert degrees to radians you multiply by pi/180. That is,d degrees = d*(pi/180) radians.
