Find the area of canvas required for a conical tent of height 24 m and base radius 7 m.
Base radius of conical tent (r)=7 m and height (h)=24 m
∴ Slant height (l)=√r2+h2=√(7)2+(24)2=√49+576=√625=25 mNow area of canvas used for it=πrl=227×7×25=550 m2
A conical tent 10 m high and tha radius of its base is 24 m . Find the slant height of the rent. If the cost of 1m2 canvas is Rs70, find the cost of canvas required to make the tent.
A circus tent is cylindrical to a height of 8 m surmounted by a conical part. If total height of the tent is 13 m and the diameter of its base is 24 m; calculate: (i) total surface area of the tent, (ii) area of canvas, required to make this tent allowing 10% of the canvas used for folds and stitching.
