Detailed Solution
Download Solution PDFदिया गया है:
दो बेलनों की त्रिज्या का अनुपात = 1 : 4
दो बेलनों की ऊँचाई का अनुपात = 4 : 3
प्रयुक्त सूत्र:
बेलन का आयतन = πr2h [जहाँ r = आधार की त्रिज्या तथा h = ऊँचाई]
गणना:
मान लें कि दो बेलनों की त्रिज्या x और 4x हैं और उनकी ऊँचाई 4y और 3y हैं।
पहले बेलन का आयतन : दूसरे बेलन का आयतन = πx2 × 4y : π(4x)2 × 3y
⇒ 4x2y : 48x2y
⇒ 1 : 12
∴ इनका आयतन 1 : 12 के अनुपात में होगा।
