Correct answer: B. 10√3 cm10√3 सेमी
Explanation
For an equilateral triangle inscribed in a circle of radius R, the side a = R√3 (since R = a/√3). With R = 10 cm, a = 10√3 cm.त्रिज्या R वाले वृत्त में अन्तर्गत समबाहु त्रिभुज की भुजा a = R√3 होती है (क्योंकि R = a/√3)। R = 10 सेमी होने पर a = 10√3 सेमी।More Mathematics & Numerical Ability questions
