Detailed Solution
Download Solution PDFदिया गया है:
घन की भुजा = 8 सेमी
प्रयुक्त सूत्र:
घन से काटे गए सबसे बड़े लंब वृत्तीय शंकु के लिए:
शंकु के आधार का व्यास = घन की भुजा
शंकु की ऊँचाई = घन की भुजा
शंकु का आयतन = 1/3 × π × r2 × h
जहाँ, r = त्रिज्या, h = ऊँचाई
परिकलन:
शंकु का व्यास = 8 सेमी
⇒ त्रिज्या (r) = 8/2 = 4 सेमी
ऊँचाई (h) = 8 सेमी
शंकु का आयतन = 1/3 × (22/7) × 42 × 8
⇒ शंकु का आयतन = 1/3 × (22/7) × 16 × 8
⇒ शंकु का आयतन = (22 × 16 × 8) / (3 × 7)
⇒ शंकु का आयतन = 2816 / 21
⇒ शंकु का आयतन ≈ 134\(\frac{2}{21}\) सेमी3
∴ 8 सेमी भुजा वाले घन से काटे जा सकने वाले सबसे बड़े लंब वृत्तीय शंकु का आयतन 134\(\frac{2}{21}\) सेमी3 है।
