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

Answer:
7919.996
Step-by-step explanation:
H = 9
D=24m
R=D/2 =12m
Therefore
Slant height (L)=√(R)^2 + (H)^2
=) √(12)^2+(9)^2
=) √144+81
=) √225
=) 15m
Cava's required for making the tent=C.S.A of tent =πrl
=) 22/7×12×15
=) (22×12×15)/7
=) 3960/7
=) 565.714m^2.
cost of 1m convas= 14
cost of 565.14m canvas = 14×565.714 = 7919.996
