समभुज त्रिकोण हा एका वर्तुळात अंतर्लिखित आहे
समभुज त्रिकोणाचे क्षेत्रफळ = 4√3 चौ. सेमी
वापरलेली संकल्पना
समभुज त्रिकोणाचे क्षेत्रफळ = \(\frac{{√ 3 }}{4}{a^2}\)
गणना
\(\frac{{√ 3 }}{4}{a^2}\) = 4√3
a2 = 16
a = 4
समभुज त्रिकोणाची परिमिती = \(\frac{a}{{\sqrt 3 }}\)
r = \(\frac{4}{{\sqrt 3 }}\)
वर्तुळाचे क्षेत्रफळ = πr2
πr2 = \(\pi \times \frac{4}{{\sqrt 3 }} \times \frac{4}{{\sqrt 3 }}\)
क्षेत्रफळ = \(\dfrac{16}{3}\pi\) चौ. सेमी
