यदि कोण \(\frac{\pi}{4}\) रेडियन है तो उसका डिग्री माप क्या होगा?
If an angle is \(\frac{\pi}{4}\) radians then what is its degree measure?
Explanation opens after your attempt
Correct Answer
B. \(45^\circ\)
Concept
\(\frac{\pi}{4}\times\frac{180^\circ}{\pi}=45^\circ\). After canceling \(\pi\), calculate \(180\div4\).
Why this answer is correct
The correct answer is B. \(45^\circ\). \(\frac{\pi}{4}\times\frac{180^\circ}{\pi}=45^\circ\). After canceling \(\pi\), calculate \(180\div4\).
Exam Tip
\(\frac{\pi}{4}\times\frac{180^\circ}{\pi}=45^\circ\) होता है। \(\pi\) कटाने के बाद \(180\div4\) करें।
