Answer:-
Pi ( ???? π) itself represents an angle of 180 degrees in radians. Since the conversion formula is Radians = Degrees × (π/180), plugging in 180 degrees gives: 180 × (π/180) = π radians This means that π radians is exactly 180 degrees. In terms of a circle, π radians represents a half-circle (or a straight angle). Since a full circle is 2π radians (360 degrees), π radians covers exactly half of it. This concept is fundamental in trigonometry, calculus, and physics, making it easier to work with angles in mathematical equations and real-world applications.
