In which quadrant does the angle 3.9 radians lie?3.9 रेडियन का कोण किस चतुर्थांश में स्थित है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Third quadrantतृतीय चतुर्थांश
Since π ≈ 3.14 and 3π/2 ≈ 4.71, we have π < 3.9 < 3π/2. Angles in this interval lie in the third quadrant.चूँकि π ≈ 3.14 और 3π/2 ≈ 4.71, इसलिए π < 3.9 < 3π/2। इस अंतराल में स्थित कोण तृतीय चतुर्थांश में होते हैं।
