## How much is 2 pi radians worth

A complete circle has 2π radians in it. Thus, 360° should be equal to 2π radians. Since 30° is 1/12 of a complete circle, 2π/12 = π/6 radians is the result. Since 90° is 1/4 of a whole circle, 2π/4 = π/2 radians is the result. One radian equals 180°/π = 57.30° because, to four … Read more
