One revolution around a circle is 360 degrees or 2*pi radians. To solve for revolutions, you set up the ratio of revolutions to radians as follows and solve for x:
x/(pi/2) = 1/(2*pi)
x=(pi/2)*(1/2*pi) = 1/4 revolutions
One complete revolution is equal to (2\pi) radians. Therefore, to find out how many revolutions equal (\pi) radians, you divide (\pi) by (2\pi), which gives you (\frac{1}{2}). Thus, (\pi) radians is equivalent to half a revolution.

One full revolution is equal to (2\pi) radians. This is because a full circle has an angle of 360 degrees, and since (360) degrees is equivalent to (2\pi) radians, we use this relationship to define a complete rotation in terms of radians.

1/2 revolution. A complete revolution is 2 x pi radians.
1 revolution = 2 x pi radians. Therefore, 1 radian = 1 / (2 x pi) revolutions.
20 times pi There are 2 pi radians in one revolution.
One revolution = tau radians (or 2*pi radians).

There are very many calculations which use pi. Many of them are in geometry: areas of circles and ellipses, volumes of solids of revolution. But there are also many applications in statistics.
