Question

how many square metre of Canvas is required for a conical tent whose height is 3.5 M and the radius of whose base is 12 metre

Answer 1

hight of conical tent = 3.5m
and radius = 12m
so
${l}^{2} = {12}^{2} + {3.5}^{2} \\ {l}^{2} = 144 + 12.25 \\ {l}^{2} = 156.25 \\ l = 12.5$
csa of conical tent
$= \pi \times r \times l \\ = 3.14 \times 12 \times 12.5 \\ = 471 {m}^{2}$
so canvas required is 471m^2

Answer 2

Answer:

Step-by-step explanation:

hight of conical tent = 3.5m

and radius = 12m

so

csa of conical tent

so canvas required is 471m^2
