Radians
A Radian is a measure of an angle, showing the relationship between the arc length and the radius of a circle:
Radians = arc length / radius The arc length of a full circle is the same as the circumference of a circle which is : c = 2 x π x r a full circle in radians is shown by: Radians = arc length / radius = 2 x π x r / r = 2 x π Degrees to Radians : Radians = degrees x pi / 180 Radians to Degrees : Degrees = radians x 180 / π Degrees : used to express directionality and angle size |
CONVERT RADIANS TO DEGREES : Radians to Degrees Formula is given as, Degrees = radians x 180 / π
Problem #1 : Convert 1.57 degrees to radians ?
