\(90^\circ\) का रेडियन माप क्या है?
What is the radian measure of \(90^\circ\)?
Explanation opens after your attempt
Correct Answer
B. \(\frac{\pi}{2}\)
Concept
\(90^\circ\) is half of \(180^\circ\), so its radian measure is \(\frac{\pi}{2}\). Half the angle means half the radian measure.
Why this answer is correct
The correct answer is B. \(\frac{\pi}{2}\). \(90^\circ\) is half of \(180^\circ\), so its radian measure is \(\frac{\pi}{2}\). Half the angle means half the radian measure.
Exam Tip
\(90^\circ\), \(180^\circ\) का आधा है इसलिए रेडियन \(\frac{\pi}{2}\) होगा। आधे कोण में रेडियन भी आधा होता है।
