A tent is in the shape of a right circular cylinder surmounted by a cone. The total height and the diameter
of the base are 13.5 m and 28 m. If the height of the cylindrical portion is 3 m, find the total surface area of
the tent.

Answer:
Diameter =28 m
Radius =2
=14 m (=r)
Height h=3 m
Curved Surface area of Cylinder =2πrh square unit
=2×7×22×14×3
=264m²
Cone:
radius =14 m; h=10.5 m
Slant height l=√h²+r²
=(10.5)2+142
=306.25
=17.5 m
Curved surface area of cone =πrl square unit
=722×14×17.5
=770m²
Total surface area of the tent =264+770=1034m
