1.	TRYTHESEthe radius of a cylinder is doubled keeping its lateral surface areane, then what is its height?ot water system (Geyser) consists of a cylindrical pipe of lenmeter 5 em. Find the total radiating surface of hot water system.XERCISE 10.2osed cylindrical tank of height 1.4 m. and radius of thg base isade up of a thick metal sheet. How much metal sheet is required (Euare meters)volume of a cylinder is 308 cm. Its height is 8 cm. Find its late
Answer» 1)Given dimensions of closed cylindrical tank areHeight =h=1.4mRadius =r=56cm=56/100 m =0.56mMetal sheet required to make cylindrical tank= total surface area of the cylindrical tank=2×pi×r(r+h)=2×22/7×0.56(0.56+1.4)=2×22×0.08×1.96=6.8992 square meters
