Question

the height of the cone shaped tent is 7 m and the radius radius of its base 24 m.how much cloth will requried to make this tent?

Answer 1

h=7 m
r=24
l²=h²+r²=49+576=625
l=25 m
csa=$\pi rl$
[tex]=3.14*24*25 \\ \\ =1884 /cm ^{2} [/tex]

1884 m² cloths needed

Answer 2

given, height of the cone  h = 7m
base radius of it  r = 24m
slant height (l) = √r²+h²
                     = √24² + 7²
                     = √625
                     = √576 + 49
                     = 25m
then surface area of cone = πrl
                                      = 22/7 ×24 × 25
                                      = 13200/7
                                      = 1885.714 m²
surface area of cone  = 1886 m² (approximately)
