answer this question.
a tent is of the shape of a right circular cylinder up to a height of 3m and then becomes a right circular cone with a maximum height of 13.5m, above the ground. calculate the cost of painting the inner side of the tent at the rate of rs.2 per sq. meter, if the radius of the edge is 24meters

Answer 1

r=14,

h of cylinder=3,

h of Cone=10.5

S.A.of cylinder=2×22/7×14×3

=264

slant height=

√10.5²+14²=

17.5

C.S.A of cone =

22/7×14×17.5

=770

T.S.A. of tent =770+264=

1034m²

cost=1034×80=82720m²
