The tent is made as a combination of right circular cylinder and right circular cone on top.Height of cylindical part of the tent = h = 3 m Radius of its base = r = 14 m Total height of the tent = 13.5 m Curved surface area of cylindical part of tent = 2πrh  2×22/7×14×3=264m2 Height of conical part of the tent = total tent - height of cylindrical part height of conical part of the conical part be I. I2=h2+r2 (used cone height)=110.25+196 =306.25 or I=17.5m Curved surface area of conical part of tent = πrI 22/7×14×17.5 = 770 Total surface of tent = Curved surface area of cylindrical part of tent + Curved surface area of conical part of tent Total surface area of tent. =264+770=1034m2 cloth required =totalsurfaceareaoftent=1034m2 cost of cloth =Rs80/m2 (given) Total cost of cloth required = Total surface area of tent x Cost of cloth  =1034×Rs80 =Rs. 82720 Cost of cloth required to make the tent is Rs. 82720
