बराबर त्रिज्या वाले एक शंकु और एक बेलन का आयतन बराबर है।
प्रयुक्त सूत्र:
बेलन का आयतन = πr2 h (r = त्रिज्या, h = ऊँचाई)
शंकु का आयतन = 1/3 πr2 h (r = त्रिज्या, h = ऊँचाई)
गणना:
मान लीजिए कि बेलन की ऊँचाई h1 है।
तो शंकु की ऊँचाई h2 है।
प्रश्न के अनुसार,
⇒ πr2 h1= 1/3 πr2h2
h2 : h1 = 3 : 1
∴ सही विकल्प 4 है।
