Answer» Given Volume of the CYLINDER = 847 m3 Formula for Volume of cylinder = πr2h ⇒ πr2h = 847 (I) Curved surface AREA of the cylinder = 242 m2 Formula for Curved surface of cylinder = 2πrh ⇒ 2πrh = 242 (II) ⇒ Dividing Equation (I) with Equation (II), we get ⇒ πr2h/2πrh = 847/242 ⇒ R/2 = 7/2 ⇒ r = 7 m Substituting the value of r in Equation 2, we get ⇒ 2 × (22/7) × 7 × h = 242 ⇒ h = (11/2) m ∴ Required ratio = h/r = (11/2)/7 = 11/14 |
