The angle subtended by an arc of length 'r' of a circle whose radius exists 'r' is comprehended as 1 radian.
The relations between sexagesimal measure (degree), centesimal measure(grade), and circular measure (radian) are
π radians = 180 Degrees
90 Degrees = 100 grades
⇒ 180 Degrees = 200 grades
Therefore, 180 Degrees = 200 grades = π radians
<h3>How radian measure related to degree measure?</h3>
To transform the value of the angle in degree, to its equivalent radians, we must multiply the given value by π/180.
For instance, the value of 180 degrees is π in radians.
In a complete rotation, the length of the intercepted arc exists equivalent to the circumference of the circle or 2πr.
Dividing the equation 180 degrees = π radians
The relations between sexagesimal measure (degree), centesimal measure(grade), and circular measure (radian) are
π radians = 180 Degrees
90 Degrees = 100 grades
⇒ 180 Degrees = 200 grades
Therefore, 180 Degrees = 200 grades = π radians
