The height of a tent is 9 m. Its base diameter is 24 m. What is its slant height? Find the cost of canvas cloth required if it costs Rs.14 per sq.m.

Answer»

Heya !!






HEIGHT of TENT ( H ) = 9 m



Diameter ( D ) = 24 m




Radius ( R ) = D/2 = 12 m







Therefore,


Slant height ( L ) = ✓(R)² + (H)²




=> ✓(12)² + (9)²



=> ✓144 + 81


=> ✓225



=> 15 m.





CANVAS required for making the tent = CSA of tent = πRL




=> 22/ 7 × 12 × 15




=> ( 22 × 12 × 15 ) / 7



=> 3960/7



=> 565.714 m².






Cost of 1 m canvas= 14

Therefore,



Cost of 565.14 m canvas = 14 × 565.714 = RS 7919.996
