Why does 2pi = 360 degrees:
In radians: Pi is the ratio  of a circle's circumference to it's diameter and is equal to 3.14... (circumference/diameter=pi). If the arc length of a radian is equal to the radius, then the length of the radius is equal to the distance of circumference used by 1 radian. Therefore we can look at the equation for the circumference of a circle. Circumference= (2) x (pi) x (radius) to know how many times the distance of the arc (the radius) fits into the circumference we divide circumference by radius. So C/R=2(pi). This means that the amount of radians that fit into the circumference of a circle is equal to 2 pi. So 2pi= total amount of radians in complete circle.
In degrees: 360 degrees is the degree of a circle because humans noticed that the constellations completed a full rotation in around 360 days (we rotated around the sun). So 360= total amount of degrees in complete circle.

Therefore: 360 degrees=2pi

- A radian is the ratio between the length of an arc and its radius in a circle
- Radian= (arc length)/(given radius)

Why does 2(pi)= 360 degrees?
-  The circumference 'C' of a circle with radius 'r' is C = 2πr.
- If r = 1, as we see in the unit circle, then C = 2π.

How many radians in 180 degrees?
- 180 is half of 360
- If there are 2π in 360 degrees, then the half of that is π

How many degrees in 1 radian?
- One radian is equivalent to 57.2958...°
- π radians = 180°
So: 1 radian = 180°/π = 57.2958...°

What is a radian?  It is a pure measure based on the radius of the circle.  It is the angle made when we take the radius and wrap it around the circle.

Why does 2(pi) = 360 degrees?  Because half of a circle is equivalent to pi (180 degrees), hence the entire circle is 360 degrees which equals 2(pi).

There are 2pi radians in 360 degreed because the formula of the circumference of a circle is 2(pi) times the radius of the circle. In 180 degrees there is 1 pi because the formula of the circumference has to be divided by two. the number of degrees in a radian is 57.296.

A radian is a scalar quantity that measures the angle limited to an arc whose length is equal to the radius of the circumference. It is another way of measuring angles, widely used in trigonometry, analytic geometry and calculus.

-Why does 2(pi) = 360 degrees?
It follows that the magnitude in radians of one complete revolution (360 degrees) is the length of the entire circumference divided by the radius, or 2πr / r, or 2π. Thus 2πradians is equal to 360 degrees, meaning that one radian is equal to 180/πdegrees.

  • What is a radian?
    • The standard unit of angular measurement is called the radian. (Often used in subjects in mathematics). The equation reasons that the length of an arc of a unit circle is numerically equal to the measurement in radians of the angle that it traverses. One radian’s value in degrees is slightly below 57.3 so when the arc length is equal to the radius, the expansion is at 180/π.

    • Why does 2(pi) = 360 degrees? And how many radians in 180 degrees?
    2(pi) is equal to 360 degrees because the value in radians of an entire circle (the entire 360 of it) is equivalent to the length of the whole circumference divided by the radius. This relationship is expressed as 2πr/r or/and 2π. Therefore, 2π radians is equal to 360 degrees,also meaning that 180 degrees is equal to π in radians. And vice verse: π radian (1 radian) is equal to 180/π degrees. 

    -How many degrees in 1 radian?
    Because 2π radians is equal to 360 degrees,also meaning that 180 degrees is equal to π in radians. The opposite is also correct: π radian (1 radian) is equal to 180/π degrees.
