एक बेलन की त्रिज्या और ऊँचाई का अनुपात 7:13 है, और इसका आयतन 6006 सेमी³ है।
π = 22⁄7
प्रयुक्त सूत्र:
बेलन का आयतन = πr²h
गणना:
माना त्रिज्या 7x है और ऊँचाई 13x है।
आयतन = πr²h
⇒ 6006 = (22⁄7) × (7x)² × 13x
⇒ 6006 = (22⁄7) × 49x² × 13x
⇒ 6006 = (22 × 49 × 13)⁄7 × x³
⇒ 6006 = 2002x³
⇒ x³ = 6006 ÷ 2002 = 3
⇒ x = ∛3
अब, त्रिज्या = 7x = 7 × ∛3 = 7 × 3\(\frac{1}{3}\) सेमी
∴ सही उत्तर 7 × 3\(\frac{1}{3}\) सेमी है।
