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.

What is the circumference of radius equals 90 FT?
C = pi*r82 C = Pi*r*2 90=R Thus 180*Pi
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.
Why multiply degree to pi by 180 to convert it to radian?
A whole circle is 360 degrees or 2*pi radians. 360 degrees = 2*pi radians so that 1 degree = pi/180 radians This gives the conversion factor of pi/180 to convert degrees to radians.
What is a 45 degree angle in terms of pi?
1/4 pi to find the degree in terms of pi, divide the degree by 180 in this example, 45 / 180 = 1/4
What times 20 equals 180?
180/20=99*20=180
How to determine theta in degrees if theta equals 0.33PI?
degrees = pi/180 180 degrees = pi .33pi = .33 times 180 = 60 degrees
An angle that egauls 180 degrees?
If you are looking for an angle in radians, then pi radians equals 180 degrees.
What is the period of y equals sin 2x?
Pi radians (180 degrees) is.
What is the circumference of radius equals 90 FT?
C = pi*r82 C = Pi*r*2 90=R Thus 180*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.
What is the length of the miror arc with an angle of 82 degrees?
radius*82*pi/180 units. radius*82*pi/180 units. radius*82*pi/180 units. radius*82*pi/180 units.
What degree is pi when measured in radians?
Pi radians is equivalent to 180 degrees.
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.
What is 240 degrees in terms of pi?
pi = 180 degrees 240 degrees = 240/180 time pi = 4 pi/3
What equals 180?
what equals 180?
What is the exact radians measure of 623 degrees?
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.
