Question

A tent is in a shape of a right circular cylinder up to a height 3m and conical above it. The total height of the tent is 13.5m and the radius of its base is 14m find yhe cost of the cloth required

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


hope it helps *

Answer 2

Heya !!!



Total height of tent = 13.5 m


Height of cylindrical part of tent (H1)= 3 m

Height of conical part of tent = Total height of tent - Height of cylindrical part of tent



=> 13.5 - 3 => 10.5 m


Height of conical part (H2)= 10.5

Radius of conical part (R) = 14 m


Slant Height (L) = ✓(H)² + (R)² = ✓(10.5)² + (14)² = ✓110.25 + 196 = ✓306.25 = 17.5 m



Radius of base of tent = 14 m



Length of clothe required to make tent = CSA of cylindrical part of tent + CSA of conical part of tent


=> 2πRH1 + πRL


=> πR( 2H + L)


=> πR ( 2 × 3 + 17.5)


=> 22/7 × 14 ( 6 + 17.5)


=> 22 × 2 ( 23.5)


=> 44 × 23.5


=>1034 m².
