\(\frac{\pi}{2}\) radians is equal to how many degrees?\(\frac{\pi}{2}\) रेडियन कितने डिग्री के बराबर है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(90^\circ\)\(90^\circ\)
Since \(\pi\) radians = \(180^\circ\), \(\frac{\pi}{2}\) radians = \(\frac{180^\circ}{2}=90^\circ\). Thus, it is a right angle and one-quarter of a complete revolution. \(45^\circ\) corresponds to \(\frac{\pi}{4}\) radians. Exam tip: multiply radians by \(\frac{180^\circ}{\pi}\) to convert them into degrees.क्योंकि \(\pi\) रेडियन = \(180^\circ\), इसलिए \(\frac{\pi}{2}\) रेडियन = \(\frac{180^\circ}{2}=90^\circ\)। अतः यह समकोण तथा एक पूर्ण चक्कर का चौथाई भाग है। \(45^\circ\) के लिए रेडियन माप \(\frac{\pi}{4}\) होता है। परीक्षा टिप: रेडियन को डिग्री में बदलने के लिए \(\frac{180^\circ}{\pi}\) से गुणा करें।
