Detailed Solution
Download Solution PDFदिया गया है:
बेलन की ऊंचाई = 6 सेमी
बेलन का आयतन = 231 सेमी3
प्रयुक्त सूत्र:
बेलन का आयतन = πr2h
जहाँ,
r = बेलन की त्रिज्या
h = बेलन की ऊँचाई
गणना:
बेलन का आयतन = πr2h
⇒ 231 = (22/7) × r2 × 6
⇒ r2 = 231 × (7/22) × (1/6)
⇒ r2 = 12.25
⇒ r = √12.25
⇒ r = 3.5 सेमी
∴ बेलन की त्रिज्या 3.5 सेमी है।
