दिलेले:
 
समभुज त्रिकोणाची परित्रिज्या 5√3 सेमी आहे.
 
वापरलेले सूत्र:
 
समभुज त्रिकोणाची परित्रिज्या = a/√3
 
समभुज त्रिकोणाची आंतरत्रिज्या = a/2√3
 
जेथे a ही समभुज त्रिकोणाची बाजू आहे
 
गणना:
 
समभुज त्रिकोणाची परित्रिज्या 5√3 सेमी आहे
 
∴ 5√3 = a/√3
 
⇒ a = 15 सेमी
 
आता, समभुज त्रिकोणाच्या आंतरत्रिज्या = a/2√3 = 15/2√3 = 5√3/2 सेमी
 
स्मार्ट युक्ती
 
आपल्याला माहिती आहे,
 
परित्रिज्या/आंतरत्रिज्या = 2/1
 
∴ आंतरत्रिज्या = परित्रिज्या/2 = 5√3/2
