एका वर्तुळात समभुज त्रिकोण अंतर्लिखित केला आहे. वर्तुळाचे क्षेत्रफळ त्रिकोणाच्या क्षेत्रफळाच्या तुलनेत किती पट आहे हे निर्देशित करणारा पर्याय निवडा.

1)3/√π
2)3π/4
3)4π/(3√3)✓ Correct
4)3

Let side of equilateral triangle be s. Radius of circumscribed circle R = s/√3. Area of circle = πR² = πs²/3. Area of equilateral triangle = (√3/4)s². Ratio of circle area to triangle area simplifies to 4π / (3√3).
